Should the internal energy of a system necessarily increase if heat is added to it?

Should the internal energy of a system necessarily increase if its tempreture is increased?

Should the internal energy of a system necessarily increase if its tempreture is increased?

Should the internal energy of a system necessarily increase if its tempreture is increased?

What is the internal energy of the system, when the amount of heat Q is added to the system and the system does not do any work during the process?

"When heat is added to a system, the internal energy of the system must increase". Justify this statement.

Calculate the changes in internal energy of a system if, 300 J of heat energy is added to the system and a work of 160 J is done on the system.

Calculate the changes in internal energy of a system if, 300 J of heat energy is added to the system and a work of 160 J is done on the system.

Calculate the changes in internal energy of a system if, 400 calorie of heat energy are added to the system and the system does 500 calories of work on the surroundings.

Calculate the changes in internal energy of a system if, 400 calorie of heat energy are added to the system and the system does 500 calories of work on the surroundings.

When 110J of heat is supplied to a gaseous system, the internal energy of the system increase by 40J. The amount of external work done (in J) is
