Heat given to a body which raises its temperature by 1 °C is known as
Explanation
Thermal capacity, also known as heat capacity, is defined as the amount of heat energy required to raise the temperature of an entire body or substance by one degree Celsius (or Kelvin). Unlike specific heat, which is an intensive property referring to the heat required per unit mass (such as one gram or one kilogram), thermal capacity is an extensive property that depends on the total mass and composition of the object. Water equivalent is the mass of water that would absorb the same amount of heat as the body for the same temperature rise, while temperature gradient refers to the rate of temperature change over a distance. Therefore, when the question specifies the heat given to a 'body' (the whole object) to raise its temperature by 1 °C without mentioning unit mass, it refers to thermal capacity.
