Answer:
The volume increases by 10.3 mL.
Explanation:
This is not an easy question to answer, because water expands at different rates depending on the temperature.
However, we can use the known densities of water at these temperatures.
(a) Calculate the <em>mass of 1 L of water at 20 °C</em>.
The density of water at 20 °C is 0.998 20 g/mL.
(b) Calculate <em>the volume at 50 °C</em>.
The density of water at 50 °C is 0.988 03 g/mL.
∴ The volume increases by 10.3 mL.
Answer:
gases (hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon and radon); one is a liquid (bromine); and a few are solids (carbon, phosphorus, sulfur, selenium, and iodine).

Can someone help me with my last question?
The speed of the yacht : 100 km/h
<h3>Further explanation </h3>
Linear motion consists of 2: constant velocity motion with constant velocity and uniformly accelerated motion with constant acceleration
- At constant velocity motion:
the speed of vo = v = constant
acceleration = a = 0
Δx = vt or x = xo + vt
An equation of constant velocity motion
x = distance = m
v = speed = m / s
t = time = seconds
A yacht sailed at a steady speed for 0.5 hours, and traveled 50 kilometers
so the velocity/speed:
Answer:
It is an example of ionic compound and ionic salt
Answer:
though many may argue that cake batter is a homogeneous mixture because of its observable uniformity, we know it is heterogeneous. ... In other words, the mixture of ingredients from cake batter results in some chemical reactions here and there, but we are still left with a mixture of things that can be separated.
