Description: What is specific heat capacity? Give the specific heat capacity of a substance, and explain what that means in terms of that substance.

Answer

The specific heat capacity of a substance is the amount of thermal energy needed to raise the temperature
of 1 $\mathrm{g}$ of the substance by $1^{\circ} \mathrm{C}$ . For example, the
specific heat capacity of aluminum is 0.21 $\mathrm{cal} / \mathrm{g} .^{\circ} \mathrm{C}$ , which means that 0.21 calof thermal energy is needed
to increase the temperature of 1 $\mathrm{g}$ of aluminum by
$1^{\circ} \mathrm{C} .$

Video Transcript

number one asks us to recap what is meant by specific heat, which is the focus of this section. Specific keep capacity can be defined as the amount of heat that is required for the amount of energy heat energy that is required to increase 1 g of a substance one degree Celsius. It could be expressed mathematically as specific. He is equal to the heat per mass per gram per change in temperature per degree Celsius. So, for example, water has a specific heat of 4.184 Jules program degree Celsius, or one calorie per graham degrees Celsius. These are just two different units of energy. So that means that we need to add 4.184 jewels to each gram of water to result in each gram of water, increasing its temperature one degree Celsius.
