The density of water is 999.73 {\rm kg/m^3} at a temperature of 10{\rm ^\circ C} and 958.38 {\rm kg/m^3} at a temperature of 100{\rm{ ^\circ C }}.Calculate the average coefficient of volume expansion for water inthat range of temperature.Express your answer using two significant figures.
One cylinder in the diesel engine of a truck has an initial volumeof 650 {\rm cm^{3}}. Air is admitted to the cylinder at 35{\rm^\circ C} and a pressure of 1.0 atm. The piston rod then does 500{\rm J} of work to rapidly compress the air.a)What is its final temperature?b)What is its final volume?
A cylinder contains 0.250 mol of carbon dioxide ({\rm CO}_{2} ) gasat a temperature of 27.0^\circ {\rm C}. The cylinder is providedwith a frictionless piston, which maintains a constant pressure of1.00 {\rm atm} on the gas. The gas is heated until its temperatureincreases to 127.0^\circ {\rm C}. Assume that the {\rm CO_2} may betreated as an ideal gas.How much work W is done by the gas in this process?
