A gas thermometer measures the temperature from the variation of pressure of a sample of gas. If the pressure measured at the melting point of lead is 2.20 times the pressure measured at the triple point of water, find the melting point of lead.

Explanation

Pressure measured at
`M_p =2.2xx pressure at triple point`
`T= P/P_tr xx 273.16`
`=( 2.2 xx P_tr)/(P_tr)xx 273.16
`=2.2 xx 273.16 = 600.952 K
=601 K
