A scale made of steel, is correct at . A certain distance measured with this scale at , is found to be . Find the error in measurement ( for steel per ).
An ideal gas is initially at temperature and volume . Its volume is increased by due to increase in temperature , pressure remaining constant. The quantity varies with temperature as
Two identical containers and with frictionless pistons contain the same ideal gas at the same temperature and the same volume . The mass of the gas in is and that in is . The gas in each cylinder is now allowed to expand isothermally to the same final volume . The change in the pressure in and are found to be and respectively. Then
The densities of a liquid at and are respectively and . A specific gravity bottle is filled with of the liquid at upto the brim and it is heated to . Then the mass of the liquid expelled in grams is (coefficient of linear expansion of glass)
The pressure that has to be applied to the ends of a steel wire of length to keep its length constant when its temperature is raised by is: (For steel Young’s modulus is and coefficient of thermal expansion is )
A metal rod is fixed rigidly at two ends so as to prevent its thermal expansion. If , and respectively denote the length of the rod, coefficient of linear thermal expansion and Young’s modulus of its material, then for an increase in temperature of the rod by , the longitudinal stress developed in the rod is
