Answer:

T₂ = 506.6 K

Explanation:

Given data:

Initial pressure of gas = 25°C (25+273 =298 K)

Initial temperature = 0.500 atm

Final pressure = 0.850 atm

Final temperature = ?

Solution:

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

0.500 atm / 298 K = 0.850 atm /T₂

T₂ = 0.850 atm × 298 K / 0.500 atm

T₂ = 253.3 atm. K / 0.500 atm

T₂ = 506.6 K

Why does the temperature remain constant during melting till all the ice has melted?
GenaCL600 [577]

All the energy goes into melting the ice. Ice and water are <em>at equilibrium</em> during melting, so the temperature does not change.

Once all the ice has melted to water, the temperature will rise.

What are 2 ways that convection currents in the oceans distribute the sun's energy?
dezoksy [38]

Answer:

When air in contact with the ocean is at a different temperature than the sea surface, heat transfer by conduction takes place. The ocean also absorbs and stores energy from the sun, and when precipitation falls, it releases heat energy into the atmosphere.

Hope it helps:)
