What is the specific heat of aluminum?

Back

0.21 cal/g°C

Front

How much heat (Q) is released when a 10 g piece of aluminum cools from 100°C to 50°C?

Back

105 J

Front

What is the formula to calculate the pressure of a gas when its volume changes at constant temperature?

Back

P1V1 = P2V2

Front

What is the relationship between volume and temperature for a gas at constant pressure?

Back

V1/T1 = V2/T2 (Charles's Law)

Front

What is the formula for calculating heat transfer?

Back

Q = mcΔT, where m is mass, c is specific heat, and ΔT is the change in temperature.

Front

What happens to the volume of a gas when the temperature decreases at constant pressure?

Back

The volume decreases.

Front

What is the Kelvin temperature of 32°C?

Back

305 K

Front

If a balloon of helium gas occupies 1 L at 32°C, what volume will it occupy at 0°C?

Back

895 mL

Front

What is the ideal gas law equation?

Back
