A 0.290 kg aluminum bowl holding 0.815 kg of soup at 25.0°C is placed in a freezer. What is the final temperature (in °C) if 391 kJ of energy is transferred from the bowl and soup, assuming the soup's thermal properties are the same as that of water?     °C

A copper sample (ccu = 387 J/kg•K) of mass mẹ = 75 g and temperature Te = 312ºC is dropped into a glass beaker that contains a mass of water me = 220 g (cw = 4190 J/kg•K). %3D The initial temperature of the water and the beaker is Tw,b = 12.0°C. What is the final temperature of the copper, beaker, and water? * The heat capacity (the specific heat times the mass) of the beaker is Cb' = 190 J/K.

One mole of oxygen gas is at a pressure of 5.45 atm and a temperature of 27.5°C. (a) If the gas is heated at constant volume until the pressure triples, what is the final temperature? °C (b) If the gas is heated so that both the pressure and volume are doubled, what is the final temperature? °C Submit Answer

If a copper pipe requires 6.7 J to raise its temperature by 1 °C, what is the quantity of heat required to raise the temperature from 25°C to 29°C?   Question options: a. 72.8 J b. 362 J c. 623 J d. 27.1 J e. 263 J

1 Thermal Expansion A steel rod is 3.000 cm in diameter at 25 °C. A brass ring has an inner diameter of 2.992 cm at 25 °C. At what common temperature – i.e., the same temperature for the rod and ring – will the ring just fit onto the rod? The coefficient of linear expansion of steel is 11 x 10-6/°C. The coefficient of linear expansion of brass is 19 x 10-6/°C.

Water at 30.0 °C is sprayed onto 0.144 kg of molten gold at 1063 °C (its melting point). The water boils away, forming steam at 100.0 °C and leaving solid gold at 1063 °C. What is the minimum mass of water that must be used? mw =
