Question

The temperature of a volume of gas is changed. in that temperature range, the gas can move in the x and z direction and rotate around the x and y-axis. No gas leaks out so the total number of particles is constant. How many degrees of freedom does this gas have? A. 2 B. 8 C. 4 D. 6 Calculate the change in thermal energy of the gas if 5.110^28 particles change from temperature 242 K to 309 K. An unknown material of mass 7.8 g is heated to 100° C and added to 153 g of water at 10° C. The system reaches thermal equilibrium at a temperature of 39° C. What is the specific heat of the object? The specific heat of water is 4.186 J/gK. How much heat must be removed from the water for Bucee's to freeze a 5 kg bag of ice? the latent heat of fusion for water is 333 J/g. How much heat must be added to 7 of water for half of it to be changed into steam (gas phase)? the latent heat of vaporization for water is 2.2610^6 J/g.

Calculate the change in thermal energy of the gas if 5.1*10^28 particles change from temperature 242 K to 309 K. 

An unknown material of mass 7.8 g is heated to 100° C and added to 153 g of water at 10° C. The system reaches thermal equilibrium at a temperature of 39° C. What is the specific heat of the object? The specific heat of water is 4.186 J/gK.
