(a) While vacationing in Europe, you feel sick and are told that you have a temperature of 40.2°C. Should you be concerned? What is your temperature in °F? (b) The morning weather report in Sydney predicts a high temperature of 12°C. Will you need to bring a jacket? What is this temperature in °F? (c) A friend has suggested that you go swimming in a pool having water of temperature 350 K. Is this safe to do? What would this temperature be on the Fahrenheit and Celsius scales?

A rectangular window in a home has a length of 1.5 m and a height of 0.80 m. If the window allows heat to escape from the home at a rate of 2,000 watts, how thick must the window be if the inside temperature of the home is 220 C and the outside temperature is 3.00C? (Assume that the coefficient of thermal conduction of glass is 0.80 W/mK.)
a.
7.1 mm
b.
124 mm
c.
9.1 mm
d.
8.1 mm
e.
11 mm
At the Chum Bucket, Plankton is trying to save money by insulating the restaurant. Instead of buying insulation, he tricks Spongebob into wedging himself between two pieces of glass 1.50m tall by 0.700m wide that are each 1.00cm thick. If the outside water has a temperature of 5.00°C and the inside water has a temperature of 23.0°C, what is Spongebob’s thermal conductivity in watts per meter degree Celsius if he is 0.110m thick and lets in 828J of heat energy per minute? Show your work.
