Question

Which of the following statements is correct? Question 3 options:

One calorie is the amount of heat necessary to raise the temperature of I gram of water by 1 Celsius degree, from 14.5 °C to 15.5 °C . The heat capacity of an object can be defined as the amount of heat needed to raise the temperature of that object by 1 C°.

The specific heat of an object is amount of heat required to change the temperature of unit mass of the object by 1 degree.

Calorimetry is based on the conservation of energy for an isolated system since no energy flows across the boundaries of the closed, isolated system

All of these statements are correct

Answer 1

All of these statements are correct.

One calorie is the amount of heat necessary to raise the temperature of I gram of water by 1 Celsius degree, from 14.5 °C to 15.5 °C . Standard definition.

The heat capacity of an object can be defined as the amount of heat needed to raise the temperature of that object by 1 C°. Standard definition.

The specific heat of an object is amount of heat required to change the temperature of unit mass of the object by 1 degree.

Calorimetry is based on the conservation of energy for an isolated system since no energy flows across the boundaries of the closed, isolated system. Heat given by one substance = heat taken by another substance.
