Question

i have some physics questions. please answer all.

1.Consider a V = 0.80-m3 open container made out of thin metal sheets with a linear expansion coefficientα = 193 × 10-6-°C-1. The container is filled to the brim with a liquid whose volume expansion coefficient isβ = 33 × 10-6-°C-1. The container and liquid are initially at a temperature of Tini = 90-°C, but are allowed to cool down to Tfin = 7.3-°C. How much of the liquid spills over as a result? You may assume that the metal sheets have zero thickness.

answer = ___________m^3

2.

A monatomic gas held at a pressure P = 1.12-atm has a molar mass M = 23-g/mol and density ρ =1.3 × 10-3-g·cm-3. Find the total internal energy of 1-mol of this gas.

answer = _________J

3.

n = 2.5-mol of diatomic gas is allowed to expand isothermally from Vini = 1.9-m3 to Vfin = 8.1-m3. The initial pressure is Pini = 0.52-atm. After this the gas is raised at a constant volume by a temperature ΔT = 46-K. Calculate the total heat flow into the gas.

answer = ____________J
