Q = mcΔT

Front

What does the equation Q = mcΔT represent?

Back

It represents the relationship between heat (Q), mass (m), specific heat capacity (c), and change in temperature (ΔT).

Front

What is the formula to calculate change in temperature (ΔT)?

Back

@@ rac{q}{mc}@@ where q is the heat added, m is the mass, and c is the specific heat capacity.

Front

What is heat?

Back

A form of energy that is transferred between systems or objects with different temperatures.

Front

In the equation Q = mcΔT, what does ΔT stand for?

Back

Change in temperature.

Front

What is specific heat capacity (c)?

Back

The amount of heat required to raise the temperature of 1 gram of a substance by 1°C.

Front

If 5000 J of heat is added to a 10 g sample with a specific heat of 0.875 J/g°C, how do you find the change in temperature?

Back

Use the formula @@ rac{q}{mc}@@.

Front

What is the unit of specific heat capacity?

Back

J/g°C (Joules per gram per degree Celsius).

Front

How do you rearrange the equation Q = mcΔT to solve for specific heat (c)?

Back

@@ c = rac{q}{mΔT}@@.

Front

What is the significance of the mass (m) in the equation Q = mcΔT?

Back

It represents the amount of substance being heated or cooled.

Front

What happens to the temperature of a substance when heat is added?

Back

The temperature increases, assuming no phase change occurs.
