Question

16) A 500-mL glass beaker of water is filled to the rim at a temperature of 0 C. How much water will overflow if the water is heated to a temperature of 95 C? (Ignore the expansion of the glass and the coefficient of volume expansion of water is 2.1 x 10-4 /C.)

17) For mercury to expand from 4.0 cm3 to 4.1 cm3, what change in temperature is necessary? Mercury has a volume expansion coefficient of 180 x 10-6 /C.

24) An ideal gas occupies 300 L at an absolute pressure of 400 kPa. Find the absolute pressure if the volume changes to 850 L and the temperature remains constant.

Explanation / Answer

16. Initial volume = 500 ml = 0.5 l = 0.5/1000 m^3

Increase in volume =initial volume * (coefficient of expansion) *95

= .00021 *500ml *95 = 9.975 ml overflows

17. Here, 0.1=4*0.000180*change in temperature

So change in temperature = 138.89 C

24. Here, P1V1=P2V2

So 400*300=P*850

So P = 141.17 kPa
