Find the change in temperature if 170 J of heat are added to2.8 mol of an ideal monatomic gas at (a) constant pressure or(b) constant volume

Find the specific heat (in joule/mole K) of a gas kept at constant volume when it takes 6 x 104 J of heat to raise the temperature of 3 moles of the gas from 54 to 213 degrees C.

(a) An ideal gas occupies a volume of 1.2 cm³ at 20°C and atmospheric pressure. Determine the number of molecules of gas in the container. molecules (b) If the pressure of the 1.2-cm³ volume is reduced to 2.2 x 10-11 Pa (an extremely good vacuum) while the temperature remains constant, how many moles of gas remain in the container? mol

An ideal monatomic gas is contained in a vessel of constant volume 0.380 m3. The initial temperature and pressure of the gas are 300 K and 5.00 atm, respectively. The goal of this problem is to find the temperature and pressure of the gas after 19.0 kJ of thermal energy is supplied to the gas. (b) Find the specific heat of the gas. __________________ J/K (d) Use the first law of thermodynamics to find the change in internal energy of the gas.__________________ kJ(e) Find the change in temperature of the gas. __________________ K
