Answer 1

Answer:

1. There are four natural state of matter

Solid, Liquid, Gas, and Plasma

2. solid is more density

3. 32°F (0°C)

4. Hence temperature of 78°C on Celsius scale is equle to 351 K on the kelvin scale

5. The pressure extra by a gas is due to random motion of particules in the gas.Gas have weak intermolecular force and the particul in continus random motion and these particles collid with the wall of the continues. The collision with the wall of the continer exerts pressure on the gas

6. The gas is collected from the atmosphere and turned into liquid within is called liqudfy goves

8. At 0°C water exists in solid state we know that the freezing point of water is 0°C the liquid from of water start ti become solid (Ice) at this temperature
