Question

Evidence A single increase in atmospheric pressure will reduce the melting point of ice by 0.0072 C . At what pressure will ice melt at a temperature of -1 C ?​

Answer 1

Explanation:

Let pressure = p

New M.P = Original M.P - (pressure × 0.0072)

Original M.P of ice = 0 C

Here New M.P = -1 C

-1 = 0 - (0.0072p)

0.0072p = 1

p = 1/0.0072 = 138.9 atm
