The medium sized puddle of spilled hot water has the highest vapor pressure because vapor pressure depends on temperature of the object.

Answer: B

Explanation

Vapor pressure, the pressure of vapor molecules of liquid exerting on the liquid surface.

It helps to determine the evaporation rate, the more the vapor pressure the more rate of evaporation will occur.

This is because the vapor pressure is the quantification of vapor molecules of the liquid on the surface of the liquid on giving an external force like heat.

The vapor pressure depends on liquid temperature and liquid surface area and pressure.

So in the given case, rainwater puddle has small surface area and room temperature, spilled hot water puddle has higher surface area as well as temperature compared to rain water puddle.

Even though the cold water puddle has large surface area but the temperature of cold water is very less compared to the temperature of hot water, so it makes the medium sized hot water puddle the one with the highest vapor pressure as the vapor pressure depends on temperature of the liquid.

Answer:

The medium-sized puddle of spilled hot water has the highest vapor pressure

Explanation:

The evaporation of water is a clear example of phase change from liquid to gas. The chemicals potentials for both phases α (liquid) and β (vapor) are functions dependig of the temperature (T) and the pressure (P) and they have the same value.

μα(T,P) = μβ(T,P)

Based in that assumption is that the equation of Clausius Clapeyron:

Ln Pv = - L/(RT) +C

Being Pv, the vapor pressure. L the vapor entalpy and R the gas constant.

So, the vapor pressure is a mere function of the temperature, thus if the temperature rises, the vapor pressure increases.

With that said, the puddle of hot water, has more temperature and thus, a higher vapor pressure.

Hope it helped!

Which piece of the planetary object data could be used to decide if there actually is a solid surface to land on?
zloy xaker [14]
A planetary surface is where the solid (or liquid) material of the outer crust on certain types of astronomical objects contacts the atmosphere or outer space. Planetary surfaces are found on solid objects of planetary mass, including terrestrial planets (including Earth), dwarf planets, natural satellites, planetesimals and many other small Solar System bodies (SSSBs).[1][2][3] The study of planetary surfaces is a field of planetary geology known as surface geology, but also a focus of a number of fields including planetary cartography, topography, geomorphology, atmospheric sciences, and astronomy. Land (or ground) is the term given to non-liquid planetary surfaces. The term landing is used to describe the collision of an object with a planetary surface and is usually at a velocity in which the object can remain intact and remain attached.

In differentiated bodies, the surface is where the crust meets the planetary boundary layer. Anything below this is regarded as being sub-surface or sub-marine. Most bodies more massive than super-Earths, including stars and gas giants, as well as smaller gas dwarfs, transition contiguously between phases, including gas, liquid, and solid. As such, they are generally regarded as lacking surfaces.

Planetary surfaces and surface life are of particular interest to humans as it is the primary habitat of the species, which has evolved to move over land and breathe air. Human space exploration and space colonization therefore focuses heavily on them. Humans have only directly explored the surface of Earth and the Moon. The vast distances and complexities of space makes direct exploration of even near-Earth objects dangerous and expensive. As such, all other exploration has been indirect via space probes.

Indirect observations by flyby or orbit currently provide insufficient information to confirm the composition and properties of planetary surfaces. Much of what is known is from the use of techniques such as astronomical spectroscopy and sample return. Lander spacecraft have explored the surfaces of planets Mars and Venus. Mars is the only other planet to have had its surface explored by a mobile surface probe (rover). Titan is the only non-planetary object of planetary mass to have been explored by lander. Landers have explored several smaller bodies including 433 Eros (2001), 25143 Itokawa (2005), Tempel 1 (2005), 67P/Churyumov–Gerasimenko (2014), 162173 Ryugu (2018) and 101955 Bennu (2020). Surface samples have been collected from the Moon (returned 1969), 25143 Itokawa (returned 2010), 162173 Ryugu and 101955 Bennu.

Flourine is found to undergo 10% radioactivity decay in 366 minutes determine its halflife​
yuradex [85]

Answer:

\boxed{\text{2408 min}}

Explanation:

The integrated rate law for radioactive decay is

\ln\dfrac{N_{0}}{N_{t}} = kt

1. Calculate the decay constant

\begin{array}{rcl}\ln \dfrac{100}{90} & = & k \times 366\\\\1.054 & = & 366k\\\\k & = & \dfrac{1.054 }{366}\\\\k & = & 2.879 \times 10^{-4} \text{ min}^{-1}\\\end{array}\\\\

2. Calculate the half-life

t_{\frac{1}{2}} = \dfrac{\ln2}{k}\\\\t_{\frac{1}{2}} = \dfrac{\ln2}{2.879 \times 10^{-4} \text{ min}^{-1}} = \text{2408 min}\\\\\text{The half-life for decay is } \boxed{\textbf{2408 min}}

What is the chemical formula for the ternary compound composed of co3+ and so42- ions? coso4 co3(so4)2 co2so4 co2(so4)3 none of
Andreas93 [3]
If you are provided with Cation and an Anion with different oxidation states, then there ratio in the formula unit is adjusted as such that the oxidation number of one ion is set the coefficient of other ion and vice versa,

Example:
               Let suppose you are provided with A⁺² and B⁻¹, so multiply A by 1 and B by 2 as follow,
                                                      A(B)₂

In statement we are given with Co⁺³ and SO₄⁻², so multiply Co⁺³ by 2 and SO₄⁻² by 3, hence,

                                                  Co₂(SO₄)₃

Result:
           Co₂(SO₄)₃ is the correct answer.
