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 reading of scale at 40°C is-
Options:
Answer:
B
Solution:
The glass scale also expands by αgΔT.
Reading=actual height/(1+0.0002)≈10.004 cm.
