Which of the following best explains what happens when you add ice to a glass of water?(2 points) The water becomes warmer because it gains heat energy from the air.

Heat energy moves from the ice cubes to the water.

Heat energy moves from the water to the ice cubes.

The ice cubes make the water colder by releasing coolness into the water.

Explanation:

That's why water cools and ice melts-

a is the answer to this question

explanation:

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
