I am not the best at this, but im pretty sure its below cloud
The temoerature decreases because the average kinetic energy is always linearly related to temperature
Answer:
2.3 atm
Explanation:
-7.50°C = 265.5 K
38°C = 315 K
(2.72)(265.5)=(pressure)(315)
pressure = 2.3 atm
It is so because warm air is lighter than cold air. Cold air means the molecules are not moving as much, so they will feel like sticking together and will not jump around as molecules in warm air will(higher temp. means higher KE). Think of a solid, colder solids are much heavier than warmer ones(think of ice-starts melting).
The different is that the galvanic cell converts chemical energy into the electrical energy and the electrolytic cell coverts electrical energy into chemical energy
