Can you determine the temperature of a vacuum? Explain
8) Considering the unusual temperature-density relationship of water between 0 °C and 4 °C, how do you expect convection to work in a camping cooler, filled with ice cubes and melted water at approximately 0 °C, and warmer soda cans?
Water close to the surface of a soda can heats up to slightly above 0 °C, thus contracts and increases its mass density, and floats downward due to gravity, being replaced by approximately 0 °C water from the top. The slightly warmed water will cool against ice cube surfaces, expand, and float upwards again.
Convection always moves a gas or liquid upward, next to a warmer surface, due to gravity.
Convection only ever takes place under gravity if you have heating from the top, and cooling from the bottom.
Convection only takes place in gases.
There is no convection in this scenario.
Water will boil spontaneously in a vacuum- on the surface of the Moon, for example . Could you cook an egg in this boiling water? Explain.

- Construct Your Own Problem Consider a person outdoors on a cold night. Construct a problem in which you calculate the rate of heat transfer from the person by all three heat transfer methods. Make the initial circumstances such that at rest the person will have a net heat transfer and then decide how much physical activity of a chosen type is necessary to balance the rate of heat transfer. Among the things to consider are the size of the person, type of clothing, initial metabolic rate, sky conditions, amount of water evaporated, and volume of air breathed. Of course, there are many other factors to consider and your instructor may wish to guide you in the assumptions made as well as the detail of analysis and method of presenting your results.arrow_forwardA 250-m-long bridge is improperly designed so that it cannot expand with temperature.
