Question

A 0.200 kg ball of glass is heated to a temperature of 82.0 Degree C and then placed in a large cake of ice at 0.00 Degree C How much of the ice will melt Calculate the number of molecules in an ideal gas contained in a volume of 3.0 times 10 m at a pressure of 448 x 10 N/m^2 and a temperature of 310 K Find that particular temperature which is unique in that it has the SAME numerical value on the Fahrenheit and Kelvin scales. What is the network done in the triangular cycle ABCA that is show in the diagram below What is the change in the internal energy of 700 moles of an ideal gas when it is heated from 270 K to 350 K?

Explanation / Answer

1.) heat gained by ice = mCT = 0.2*0.840*82

energy required to convert ice into water at 0 degree = m*deltaH

m*delta H = 0.2*0.84*82

m*334 = 0.2*0.84*82

m= 0.103 Kg = 103.11 gram
