In part 3 of the lab, you discovered the relationship between temperature (T) and volume (V) of a gas.

rewona [7]

$\frac{V1}{T1}$ = k

<u>Explanation:</u>

The relation between volume, V of gas and Temperature, T of a gas is related by Charles Law.

This law states that the volume of a given amount of gas held at a constant pressure is directly proportional to the Kelvin temperature

Thus,

$\frac{V}{T}$ = k

where k is a constant

Therefore,

$\frac{V1}{T1}$ = $\frac{V2}{T2\\}$ = $\frac{V3}{T3}$ ...

This shows, as the volume of a gas goes up, the temperature also goes up and vice-versa.

Ganezh [65]

Answer:

Explanation:

use this fromula

q = m c ∆t

m is mass of silver =50 g

∆t is difference in temperature= 255-106=149
