The pressure on 0.2 kg of water is increased reversibly and isothermally from atmo- spheric pressure to 3 × 108 Pa at 20°C. (Numerical values are given in Table 9.6.) (a) How much heat is transferred?

A gas burner transfers 9.20 × 105 J into a block of ice with a mass of 2.29 kg and an initial temperature of 0°C. (a) How much of the energy (in J) supplied by the burner goes into melting all the ice into liquid water? (Enter you answer to at least three significant figures.) 769440 Melting is a phase change from solid to liquid and requires an energy transfer of Q = mLf where Li latent heat of fusion. Freezing is a phase change from liquid to solid and requires an energy transfer of Q = -mLf. In freezing, the energy transfer is negative because energy is removed from the substance. J (b) How much of the energy (in J) supplied by the burner goes into raising the temperature of the liquid water? (Er your answer to at least three significant figures.) 1.57E+5 X Think about conservation of energy. The total energy supplied is known, and you found in part (a) the energy t goes into melting. How much is left over? J (c) What is the final temperature of the liquid water in degrees Celsius?…

A storage building with well-insulated walls and containing 750 m³ of air at 275 K is heated at constant pressure (atmospheric). Consider air to be an ideal diatomic gas. (a) Determine the energy (in kJ) required to increase the temperature of the air in the building by 2.30°C. kJ (b) Determine the mass (in kg) this amount of energy could lift through a height 2.30 m. kg

Consider the change in the internal energy of a system. -What is the change in the internal energy, in joules, of a system that does 4.725 × 105 J of work, while 3.2 × 106 J of heat is transferred into the system and 7.8 × 106 J of heat is transferred from the system to the environment?
