The temperature of a room heated by heater is `20^@C` when outside temperature is `-20^@C` and it is `10^@C` when the outside temperature is `-40^@C`. The temperature of the heater is

A radiator whose temperature is T^(@)C is used to heat the room in the cold weater The radiator is able maintain a room temmperature of 30^(@)C when ouside temperature is 10^(@)C and 15^(@)C when outside temperature is 30^(@)C Determine the temperature of the radiator [Assume Newton's law of cooling to be valid] .

If the room temperature is 20 °C then the temperature on Fahrenheit scale is

If the temperature in a room is 20^@C , what s its temperature in degree Fahrenheit?

The amount of heat conducted out per second through a window, when inside temperature is 10^(@)C and outside temperature is -10^(@)C , is 1000 J. Same heat will be conducted in through the window, when outside temperature is -23^(@)C and inside temperature is:

A room is heated by a radiator that has a constant temperature T (unknown). When the outside temperature is 260 K, the room temperature is 300 K. However, when the outside temperature drops to 240 K, the room temperature is only 290 K. Estimate the radiator temperature T.

If the temperature of City A is -20 ""^(@)C and the temperature of City B is 10 ""^(@)C , the difference in temperature between the two cities is
