What is the ideal gas constant (R) in L⋅atm∕mol⋅K?

Back

0.0821 L⋅atm∕mol⋅K

Front

What phase change represents a decrease in entropy?

Back

Gas to liquid

Front

What is the specific heat of water in J/kg∙°C?

Back

4,186 J/kg∙°C

Front

What is a unique quality of gases?

Back

Gases spread out to fill all available space, can be compressed, and take the shape of their container.

Front

How do you convert Kelvin to Celsius?

Back

C = K - 273.15

Front

What is the formula to calculate heat (Q) required to change the temperature of a substance?

Back

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

Front

What is the relationship between pressure and volume in gases at constant temperature?

Back

Boyle's Law: P1V1 = P2V2.

Front

What is the first law of thermodynamics?

Back

Energy cannot be created or destroyed, only transformed.

Front

What is enthalpy (H)?

Back

Enthalpy is the total heat content of a system, defined as H = U + PV, where U is internal energy, P is pressure, and V is volume.

Front

What is the significance of the phase diagram?

Back

A phase diagram shows the states of a substance at different temperatures and pressures.
