Is the heat supplied to a system always equal to the increase in its internal energywhat thermodynamic variable is defined by zeroth law and first law of thermodynamic?

The heat supplied to a system can increase its internal energy if no work is extracted from the system. If any work is done by the system, then the increase in internal energy will be less than the heat supplied to the system. The thermodynamic variable defined by the zeroeth law is Temperature.

Distinguish between heat and internal energy?

Heat is defined as "energy in transit owed to a difference in temperature". The "internal energy" (or intrinsic energy) is the sum of the energy of all the atoms or molecules in a given body. In gases it includes the molecules or atoms kinetic energy (translation energy), rotational energy, vibrational energy, electronic energy... Solids lack the kinetic and rotational energies. Internal energy is thermal energy. So is heat, but heat is thermal energy in motion due to a difference in temperature.
