Question
The temperature of the system does not change. Such a system is called ________.
- Isothermal
- Adiabatic
- Isochoric
- Isobaric
Hint:
Adiabatic processes occur when no heat is exchanged between the system and the environment,
The correct answer is: Adiabatic
The temperature of the system does not change. Such a system is called adiabatic. An adiabatic process is defined as a process in which no heat transfer takes place. This does not mean that the temperature is constant, but rather that no heat is transferred into or out from the system.

Energy is the ability to do work which is measured in different units. Calorie and Joule are the units of energy which are proportionate to each other. This implies any change in the value of calories will change its equivalent value in joules. The relation between calorie and joule can be numerically written as : 1 calorie = 4.2 joules approx.
Hence, 625 cal= (625* 4.2)= 2,615 joules.

25 kcal = ____cal
The kilo calorie is a measurement unit of energy. The symbol of kilo calorie is kcal.The kilocalorie is used in measuring the heating, calorific value or metabolizing foods. It equals to 1000 calories, or approximately 4.2 kilojoules. Therefore, 1 kcal= 1000 cal.
so, 25 kcal= (25*1000)= 25000 cal.

When sufficient heat is supplied to an ice cube
When heat is applied to an ice molecule, the solid phase changes to the liquid phase and thus the ice is melted into water after applying heat. Heating a substance makes the molecules move faster and thus the heat energy breaks the hydrogen bonds that hold the molecules in the ice together thus resulting in melting of ice.
