A 4-m x 5-m x 6-m room is to be heated by a baseboard resistance heater. It is desired that the resistance heater be able to raise the air temperature in the room from 7°C to 25°C within 15 minutes. Assuming no heat losses from the room and an atmospheric pressure of 100 kPa, determine the required power rating of the resistance heater. Assume constant specific heats at room temperature.

-am. The piston is quickly pushed into the cylinder, which compresses the air inside the cylinder, dramatically A fire sy Increasing the temperature. This causes a small piece of material, such as cotton, in the cylinder to burn. A fire syringe has a cylinder with an initial volume of 10.0 cm, an initial pressure of 1.0 atm, and an initial temperature of 300. K. The piston is pushed down, which decreases the volume to 1.0 cm and increases the temperature to 510. K. Which of the following indicates the final pressure inside the cylinder and helps explain the pressure? The pressure decreases to 0.41 atm; the gas particles in the cylinder hit the walls of the cylinder with less speed. B The pressure remains constant at 1.0 atm; the changes in volume and temperature cancel each other ot. The pressure increases to 5.9 atm; the gas particles in the cylinder hit the walls of the cylinder with greater speed. D The pressure increases to 17 atm; the gas particles in the cylinder hit the walls of…
