The temperature inside a refrigerator is t 2°C and the room temperature is t 1°C. The amount of heat delivered to the room for each joule of electrical energy consumed ideally will be
The temperature inside a refrigerator is 4oC and the room temperature is 27oC. How many joules of heat will be delivered to the room for each joule of electricity consumed by the refrigerator?( Treat the refrigerator as ideal).
The current-voltage graph for a given metallic wire at two different temperatures T1 and T2 is shown in the figure. The temperature T1 and T2 are related as:
The figure shows graphs of pressure versus density for an ideal gas at two temperature T1 and T2 which is correct?
