An ideal diatomic gas undergoes a polytropic process governed by the equation P∝Vn in which it absorbs 100 J heat and performs 25 J work. What is the value of 4n⋅20304050

The molar specific heat of a diatomic ideal gas at constant volume is Cv = 5/2 R. What is the heat needed to heat 28.00 g of nitrogen gas from 20.00 °C to 85.00 °C?

One mole of an ideal monatomic gas is taken through a thermodynamic process shown in the P-V diagram. The heat supplied to the system in this process is K×(180/2+10)P0V0. Determine the value of K.

A quantity of a monatomic ideal gas undergoes a process in which both its pressure and volume are increased by a factor of n = 3 as shown in the figure below. What is the energy absorbed by heat into the gas during this process? Hint: The internal energy of a monatomic ideal gas at pressure P and occupying volume V is given by U = 32PV. (Give your answer as a multiple of P0V0.) Your response differs from the correct answer by more than 10%. Double check your calculations. ✕ P0V0

The reaction below represents the decomposition of a generic diatomic molecule in its standard state.1/2 A2(g) → A(g)Assuming that the standard molar Gibbs energy of formation of A(g) is 8.12 kJ•mol–1 at 2500 Kand –72.20 kJ•mol–1 at 3500 K, determine the value of ΔH°rxn for these data assuming that ΔH°rxn is independent of temperature. Express your answer in kJ, in one decimal place.

A heater supplies 10.2 kJ of thermal energy is to heat 80 grams of ice at 0C. The specific latent heat of fusion of ice is 340 J/g. How much ice remains after heating?
