Wood is a compound. It is not part of the periodic table so it is not an element nor is it a mixture of any other compounds. It is also directly cut from its place in nature.

a gas in a container with a fixed volume was originally at a pressure of 317kpa and a temperature of 154k. what is the new press
goldfiish [28.3K]
<h2>Hello!</h2>

The answer is: 4.77atm

<h2>Why?</h2>

Since there's a fixed volume, we can use the the Gay-Lussac's Law which stablish a relation between the pressure and the temperature:

\frac{P}{T}=k

<em>P</em> is the volume of the gas

<em>t</em> is the temperature of the gas

<em>k </em>is the proportionality constant

We also have the following equation:

\frac{P1}{T1}=\frac{P2}{T2}

Where:

P2=\frac{P1*T2}{T1}=\frac{317kPa*235K}{154K}=483.73kPa

We are asked to find the pressure in atm, so we must convert 483.73kPa to atm:

1kPa=0.009869atm

Then,

483.733kPa*\frac{0.009869atm}{1kPa}=4.77atm

Have a nice day!

Determine whether each substance will sink or float in corn syrup, which has a density of 1.36 g/cm3. Write “sink” or “float” in
kondor19780726 [428]

Answer:

Here's what I get

Explanation:

A substance with ρ < 1.36 g/cm⁻³ will float on corn syrup.

A substance with ρ > 1.36 g/cm⁻³ will sink in corn syrup

\begin{array}{rrr}\textbf{Substance} & \mathbf{\rho/g\cdot \textbf{cm}^{-3}}& \textbf{Sink/Float}\\\text{Gasoline} & 0.75 & \text{Float}\\\text{Water} & 1.00 & \text{Float}\\\text{Corn syrup} & 1.36 & -\\\text{Honey} & 1.42 & \text{Sink}\\\text{Titanium} & 4.54 & \text{Sink}\\\end{array}
