Q

Front

What is the definition of Specific Heat?

Back

The amount of energy required to raise the temperature of 1 kg of a substance by 1ºC.

Front

Which object will heat up faster: an object with a specific heat of 4.45 J/gºC or one with 1.82 J/gºC?

Back

The object with a specific heat of 1.82 J/gºC will heat up faster because it has a lower specific heat.

Front

What is the formula for calculating change in temperature using the heat equation?

Back

Q/mC_p= ∆T

Front

What are the SI units for Specific Heat?

Back

J/g°C, J/Kg°C, Cal/g°C.

Front

What does a higher specific heat indicate about a substance's ability to absorb heat?

Back

A higher specific heat indicates that the substance can absorb more heat without a significant change in temperature.

Front

How does specific heat affect temperature change in substances?

Back

Substances with lower specific heat will experience a greater temperature change when the same amount of heat is added compared to those with higher specific heat.

Front

What is the relationship between specific heat and thermal conductivity?

Back

Specific heat is a measure of how much heat energy a substance can store, while thermal conductivity measures how quickly heat can pass through a material. They are related but represent different properties.

Front

What is the specific heat of water?

Back

The specific heat of water is approximately 4.18 J/gºC.

Front

How does the specific heat of metals generally compare to that of non-metals?

Back

Metals generally have lower specific heat values compared to non-metals, meaning they heat up and cool down more quickly.
