A. The molecules start packed together very tightly in a solid. Then when it turns to water, the molecules can move around each other freely, but still contained. When water turns to vapor, the molecules are going crazy moving around. They are not contained at all and bounce of of each other freely.
b. The temperature rises. (ice turns to water at 33 degrees and water turns to vapor at 212 degrees)
Answer:
The Mass of a person is calculated to be 28.6kg .
Explanation:
This is based on Kinetic energy and we know, that Kinetic energy is the energy possessed by body by virtue of its motion .
It can be calculated by expression :
K.E=1/2mv²
Velocity of a person = 11.2m/sec
Kinetic energy = 1800J
Mass of person = ?
We know ,
K.E=1/2mv²
so, putting values we have :
1800=1/2 x m x (11.2)²
That is ,
m=1800 x 2 /11.2 x 11.2
or
m=3600/125.44
m = 28.6 kg
Temperature and pressure can change the solubility of a solute.
Answer:
The axis is tilted and points to the North Star no matter where Earth is in its orbit. Because of this, the distribution of the Sun's rays changes. ... It also means that the angle at which sunlight strikes different parts of Earth's surface changes through the year.

The resistance of the coil is 12. 97 Ω
<h3>How to determine the length</h3>
The formula for resistance is given as;
R = V/I
Note that resistance, R is measured in Ohms and represented with the symbol ( Ω)
Where;
- V is the voltage = 120 V
- I is the current = 9. 25 A
Substitute the values into the formula
R = 120/ 9. 25
R = 12. 97 Ω
The resistance, R is 12. 97 Ω
Hence, the resistance of the coil is 12. 97 Ω
