Melting!!!

Explanation:

Melting is just like this. When a solid's atoms are in place, they are like the oranges before - Carefully organized, not moving much, in a structure.

When a solid starts melting into a liquid, the molecules start bouncing off each other, collapsing. :)

So, the answer is <u>Melting!</u>

Answer:

The answer to your question is: P2 = 846 kPa

Explanation:

Data

V1 = 2.5 l

P1 = 300 kPa

T1 = 273 °K

P2 = ?

V2 = 1 l

T2 = 308°K

Formula

$\frac{P1V1}{T1} = \frac{P2V2}{T2}$

$P2 = \frac{P1V1T2}{T1V2} \\$

$P2 = \frac{(300)(2.5)(308)}{(273)(1)} \\$

$P2 = \frac{231000}{273} \\$

P2 = 846 kPa

A total of 620 C of charge passes through a flashlight in 0.510 h. What is the average current in milliamperes?

aniked [119]

Explanation:

The given data is as follows.

Q = 620 C, t = 0.510 hour

First, we will convert hours into seconds. Since, there are 3600 seconds present in 1 hour. Hence, number of seconds present in 0.510 hour are as follows.

$0.510 hr \times \frac{3600 sec}{1 hr}$
