After you drive for a while your tires will gain some energy via friction and heat up. If the air inside the tires absorbs 150 Joules of energy by heat, and does 100 Joules of work by expanding and lifting your car a fraction of a millimeter, what is the net change in the internal energy of the air inside the tires? (Hint: Use the first law of thermodynamics) 100 Joules 50 Joules 250 Joules 150 Joules

Given
Heat added Q=150 J
Work done by gas W=100 J
By first law of thermodynamics
U = Q W U = 150 100 = 50  J
Change in internal energy of air is 50J
