Front

What is the Zeroth Law of Thermodynamics?

Back

If two objects in the same system are at the same temperature, the system is in thermal equilibrium.

Front

What does the Second Law of Thermodynamics state?

Back

Energy always flows from high to low.

Front

What is the specific heat equation?

Back

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

Front

What is the value of specific heat capacity of water?

Back

Approximately 4186 J/(kg·°C).

Front

How do you convert Fahrenheit to Celsius?

Back

Use the formula: C = (F - 32) × 5/9.

Front

What is thermal equilibrium?

Back

A state in which two objects in contact do not exchange heat because they are at the same temperature.

Front

What is the First Law of Thermodynamics?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the definition of heat?

Back

Heat is the energy transferred between systems or objects with different temperatures.

Front

What is the mass (m) in the specific heat equation if 2500J of energy is added to 0.6kg of water?

Back

0.6 kg.

Front

What is the value of Q in the specific heat equation if 2500J of energy is added?

Back

2500 J.
