Answer to Question #80114 in Physics for Vaibhavi Desai

Question

1a) Calculate the increase in volume of 100cm^3 of murcury when its temperature changes from 10°C to 35°C. The volume coefficient of expansion of murcury, B is 0.00018°C^-1

b) Determine the change in volume of a block of cast iron 5.0cm × 10cm × 6.0cm, when the temperature changes from 15°C to 47°C. The coefficient of linear expansion, a for cast iron is 0.000010°C^-1.

c) A glass flask is filled "to the mark" with 50.00cm^3 of murcury at 18°C. If the flask and its contents are heated to 38°C, hoe much murcury will be above the mark? The coefficient of linear expansion a, for glass is 9.0 × 10^-6°C^-1 and the coefficient of volume expansion, B for murcury is 182×10^-6°C^-1.

Take B = 3a glass as a good approximation
i) Determine the change in volume of the murcury

ii) Determine the change in volume of the glass

iii) Calculate how much mercury will be above the mark
