For Q14-Q16: at 20°C a liquid fills a glass container to height 10 cm. Container length is 20 cm and cross-sectional area 100 cm². The scale is correct at 20°C. Liquid volume expansion coefficient is 5×10^-5 K^-1 and glass linear expansion coefficient is 1×10^-5 °C^-1.

The actual height of liquid at 40°C is-

Options:

Answer:
B
Solution:

Container area expands by 2αgΔT, so area becomes 100(1+0.0004).

Actual height=1001/100.04≈10.006 cm.
