🌹An iron rod is 1.58m long at 0°C,what must be the length of a brass rod at 0°C if d difference between the lengths of the two rods is to remain the same at all temperatures?
linear expansivity of iron 1.2*10^-5
brass 1.9*10^-5
🌹A glass bottle filled with mercury has mass 500g. on being heated through 35°C,2.43g of mercury are expelled.calculate the mass of mercury remaining in the bottle
cubic expansivity of mercury is 1.8*10^-4
linear expansivity of glass is 8.0*10^-6.
please help.?
