The difference between the length of a certain brass rod and that of a steel rod is claimed to be constant at all temperatures.Is it possible?

What is the difference between heat and temperature?

A steel tape 1m long is correctly calibrated for a temperature of 27.0 ^@C . The length of a steel rod measured by this tape is found to be 63.0 cm on a hot day when the temperature is 45.0 ^@C . What is the actual length of the steel rod on that day? What Is the length of the same steel rod on a day when the temperature is 27.0 ^@C ? Coefficient of linear expansion of steel = 1.20xx10^-5 K^-1 .

The length of a copper rod at 20°C is found to be 150cm when measured with a steel scale which gives correct reading at this temperature.What length of the same copper rod be found when measured with the same rod at 60°C?

which of the following cylindrical rods will conduct most heat,when their ends are maintained at the same steady temperature?

A large steel wheel is to be fitted on to a shaft of the same material. At 27 ^@C , the outer diameter of the shaft is 8.70 cm and the diameter of the central hole in the wheel is 8.69 cm. The shaft is cooled using ‘dry ice’. At what temperature of the shaft does the wheel slip on the shaft? Assume coefficient of linear expansion of the steel to be constant over the required temperature range: a_ steel = 1.20 xx 10^-5K^-1 .

Form the equation from the folllowing: The difference between length and breadth of a room is 3m and its area is 270 Sq.m. Find the length and breadth of the room.

A metal and is heated till its length becomes twice of its original length. If coefficient of linear exansion of the material of the rod is alpha , then what is the change in temperature?

Assume the thermal conductivity of copper is 4 times that of brass.Two rods of copper and brass having the same length and cross section are joined end to end.The free and end of copper is at 0°C and the free end of brass is at 100°C.Calculate the temperature of the junctionof thw two rods at equilibirum.
