A sample of gas with a volume of 30.0 ml at 25.0 °c is heated to 50.0 degrees celsius. what is the new volume of the gas?

Answer : The new volume of the gas is, 32.5 mL

Explanation :

Charles' Law : It states that volume of the gas is directly proportional to the temperature of the gas at constant pressure and number o moles of gas.

Mathematically,

where,

are the initial volume and temperature of the gas.

are the final volume and temperature of the gas.

We are given:

Putting values in above equation, we get:

Therefore, the new volume of the gas is, 32.5 mL

c is the answer because when something is left after something evaporates that shows the chemical change.
