Detailed explanation-1: -specific heat, the quantity of heat required to raise the temperature of one gram of a substance by one Celsius degree. The units of specific heat are usually calories or joules per gram per Celsius degree. For example, the specific heat of water is 1 calorie (or 4.186 joules) per gram per Celsius degree.

Detailed explanation-2: -Heat capacity is the amount of heat required to change the temperature of a given amount of matter by 1°C. The heat capacity of 1 gram of a substance is called its specific heat capacity (or specific heat), while the heat capacity of 1 mole of a substance is called its molar heat capacity.

Detailed explanation-3: -Answer and Explanation: False. The specific heat of a substance is the energy required to change the temperature of the substance and not its phase.

Detailed explanation-4: -Specific heat doesn’t depend on heat given because required heat energy for unit mass per rise of 1℃ can be calculated from the given heat energy to get specific heat.

Detailed explanation-5: -The specific heat capacity is intensive, and does not depend on the quantity, but the heat capacity is extensive, so two grams of liquid water have twice the heat capacitance of 1 gram, but the specific heat capacity, the heat capacity per gram, is the same, 4.184 (J/g.K).
