  • Step 1: Write the equation as it is usually given. Step 2: Because the unknown quantity—volume—is in the denominator, multiply both sides of the equation by volume (V). The equation will still be true, and volume will be on the left side where you want it. Step 3: Divide both sides of the equation by density (D).

  • The heat capacity terms in Table B.10 have units of J/g-atom C because they apply to atomic species instead of molecular species. 1 mole of water contains 2 g-atoms of H and 1 g-atom of O. So to estimate the heat capacity of liquid water, if you multiply the heat capacity term for H (18) by 2 g-atoms and add the term for O (25) The bowl has a mass of 0.75 kg and a specific heat capacity of 8 5 0 / ⋅ J k g C ∘. The soup has a mass of 0.95 kg and a specific capacity of 4, 1 8 0 / ⋅ J k g C ∘. Find the average rate of heating of the table and the air around it. Give your answer to the nearest watt.
  • The specific heat capacity, often called simply specific heat, is the heat capacity per unit mass of a material. From this definition we have the following formula for specific heat:, where c — specific heat, Q — heat added or removed to the body, m — mass of the body, ΔT — temperature change.
  • This (1 cal/g.deg) is the specific heat of the water as a liquid or specific heat capacity of liquid water. One calorie= 4.184 joules; 1 joule= 1 kg(m) 2 (s) -2 = 0.239005736 calorie The specific heat capacity of water vapour at room temperature is also higher than most other materials.

Heat is a form of energy and is measured in joules (J). It is also called thermal energy. It tells you how much energy (in the form of heat) is stored in an object; this depends on the object's temperature, material and mass. When heat energy flows from a hot object to a cooler one, we say that heat is transferred.
