The pressure of the gas in a constant vo...

The pressure of the gas in a constant volume gas thermometer is 80cm of mercury in melting ice at `1 atm`. When the bulb is placed in a liquid, the pressure becomes `160cm` of mercury. Find the temperature of the liquid.

Text Solution

Verified by Experts

The correct Answer is:
C, D
At constant volume,
`p prop T`
`:. (p_1)/(T_1) = (p_2)/(T_2)`
`:. T_2 = ((p_2)/(p_1)) T_1`
= `((160)/(80))(273) = 546 K`.
