Chapter 19: Problem 2

Could you heat the kitchen by leaving the oven open? Explain.

Short Answer

Expert verified
Yes in a sense, leaving the oven open will release heat into the kitchen and can cause a temporary increase in temperature in the immediate vicinity. However, due to factors such as the size of the kitchen and the small opening of the oven, it would not effectively warm the entire kitchen.

Step by step solution

01

Understanding Convection

Convection is the transfer of heat within a gas (or a liquid) where the hotter part of the gas or liquid rises to the top due to expansion and the relatively cooler gas or liquid falls to the bottom. In the case of the oven, it's enclosed space causes the air inside to heat up and expand.
02

Oven and Heat Transfer

When the oven door is opened, the hot air inside the oven tends to rise, due to its lower density. This is why when we open the oven's door we feel a surge of heat.
03

Heating the Kitchen

As the hot air from the oven disperses into the kitchen, it can temporarily warm the immediate surrounding area. However, given the size of typical kitchens and the relatively small opening of the oven door, the overall effect on the temperature of the entire kitchen would be minimal. This is because of the limited amount of heat that can be produced by an open oven compared to the volume of air in the kitchen.

Name some irreversible processes that occur in a real engine.

The temperature of \(n\) moles of ideal gas is changed from \(T_{1}\) to \(T_{2}\) at constant volume. Show that the corresponding entropy change is \(\Delta S=n C_{V} \ln \left(T_{2} / T_{1}\right)\)

Refrigerators remain among the greatest consumers of electrical energy in most homes, although mandated efficiency standards have decreased their energy consumption by some \(80 \%\) in the past four decades. In the course of a day, one kitchen refrigerator removes \(30 \mathrm{MJ}\) of energy from its contents, in the process consuming \(10 \mathrm{MJ}\) of electrical energy. The electricity comes from a \(40 \%\) efficient coal-fired power plant. The refrigerator's COP is a. \(\frac{1}{3}\) b. 2 c. 3 d. 4

Why do refrigerators and heat pumps have different definitions of COP?

Why doesn't the evolution of human civilization violate the second law of thermodynamics?
