The calories of chicken breast: 1330 kcal/kg (5565 kJ/kg)

The calories of boiled vegetables: 170 kcal/kg (710 kJ/kg)< /p>

The calories of apples: 520 kcal/kg (2175 kJ/kg)

Then:

The calories of 175 grams of chicken breast are: 232 kcal (973 Kilojoules)

The caloric value of 200 grams of boiled vegetables is: 34 kcal (142 kJ)

The caloric content of 2 apples (200 g) is: 104 kcal (435 kJ) )

Total calories are: 370 kcal (1550 kilojoules)

Note: kcal is the metric unit of heat (domestic use), and kilojoules is the imperial unit of heat (international use).

What is heat:

Heat refers to when the change in the state of the system comes from the destruction of thermal equilibrium conditions, that is, when there is a temperature difference between the system and the outside world, we call it There is thermal interaction between the system and the outside world. The result of the action is that energy is transferred from the high-temperature object to the low-temperature object. The energy transferred at this time is called heat. Heat and work are two different forms of energy transfer that occur during system state changes. They are measures of different forms of energy transfer. They are both related to the intermediate process of state change and are therefore not functions of the system state.
