Answer 2

Answer:

20.752

Explanation:

To increase the temperature u will let's say heat the gas (cuz u can by compressing the gas). The thermal energy you supply when heating is itself changed to kinetic energy possessed by the molecules of the gas. The change in internal energy therefore will be equal to the increase in kinetic energy* which is equal to the thermal energy u supply.

*(Assuming helium is an ideal gas in which internal energy is equal to kinetic energy only , whereas in fact internal energy is the sum of potential and kinetic energies).

Calculation time!!!Now how do calculate how much energy u need to supply?

Using this equation: E=mcT

E is our unknown energy

M is the mass (number of moles x Ar of Helium)

T is the change in temperature

c is the specific heat capacity of the substance and is a constant. Here it is helium and it's c is 5.188 J g^-1 C^-1

Substituting the values…..

E= 4x5.188x1 = 20.752 J

Congratulations we are done !!
