What is gay lussas law

galben [10]

<u>Gay lussas law:</u>

Gay-Lussac law states that the pressure for a given gas’ mass changes directly to an absolute gas temperature, provided that the volume held to be constant. The mathematical expressions of Gay-Lussac law also correspond to those of Charles Law:

$\frac{P}{T} \text { or } \frac{P_{1}}{T_{1}}=\frac{P_{2}}{T_{2}}$

This gas law is important because it shows that an increase in gas temperature increases the pressure proportionally (if the volume does not change). Similarly, as the temperature decreases, the pressure decreases proportionally.

PLEASEE HELPP!

I heard of this before I think I know the answers.

1st one, I'm thinking D. Because Turning Liquid into a Solid means like it would take energy out since its freezing.

2nd one, I would choose A
B and C why would they slow down if they were still in a solid. they attracted one another, but they stood still(Didn't move). D is explaining how Liquid turns into a Solid, so this is definitely incorrect. So I would choose A.

I really do hope this helps you out. (Idk about the 1st, but 2nd I think its the answer)

A person applies a force of 200 N over 1.5 m to a jack. The jack exerts a 1000-N force on a car a distance of 0.02 m. What is th

Answer:

The efficiency rating of the jack is 0.067.

Explanation:

We have, a person applies a force of 200 N over 1.5 m to a jack. The jack exerts a 1000-N force on a car a distance of 0.02 m.

It is required to find the the efficiency rating of the jack. It is equal to the ratio of output work to the ratio of input work. So,

$\eta=\dfrac{1000\times 0.02}{200\times 1.5}\\\\\eta=0.067$

Thus, the efficiency rating of the jack is 0.067.
