Which statement describes the energy changes that occur when water in a tea kettle is heated on a stove that uses natural gas?
telo118 [61]

Answer: Some of the chemical energy in natural gas transforms into thermal energy, which heats the water. Then some of the thermal energy changes into sound energy when the water forms steam and the steam leaves the kettle.

Explanation:

The natural gas consists of chemicals, which when burn produces thermal energy. This thermal energy is utilized for heating or boiling water. The boiling water produces steam the steam tries to come out of the kettle thus makes sound over the kettle lid, the pressure created by steam while leaving kettle produces sound energy.

An insulated tank contains air at 0.5 atm pressure and 298K. The outside pressure is at 1 atm pressure and 298K. A valve is open
aalyn [17]

Answer:

The temperature of the gas after it is filled is 596 K

Explanation:

According to Gay-Lussac law, the pressure of a gas mass is directly proportional to temperature to a constant volume. That means than if pressure rise, the temperature too. We can assume then the volume is constant because the tank is isolated. The tank will be full when pressure will be in equilibrium, that means when pressure will be 1 atm because it is environment pressure. Using the following equation:

P1 /T1 = P2 /T2 and replacing, T2 = P2  *T1 / P1 = 1 atm * 298K / 0.5 atm = 596 K.

I hope my answer helps you
