Question 1 options:
gas, solid, liquid
gas, liquid, solid
solid, liquid, gas
solid, gas, liquid
The state of matter with an indefinite shape and definite volume is _____.
Question 3 options:
Solid
liquid
gas
plasma
plasma
Deposition and condensation is an example of an endothermic reaction
Question 7 options:
True
False
Which one of the following statements best describes the particles in a gas?
Question 8 options:
They are very close together and are able to vibrate.
They are stationary and not able to vibrate
They are moving very slow and are far apart.
They are moving very fast and are far apart.
Question 1'sanswer is gas, liquid, and solid.
Why? Think about it - solids hold better than any of those two - And gasses hold the weakest and liquid goes in the middle :)
Question 3 is liquid, because if you put like, we'll say water, if you put water into a round bottle it would look round, right? It would go for any other shaped bottle - It would look like that same shape. But you can't change the volume - It will always be the same
Question 7 is FALSE - They're actually exothermic reactions. :)
Last question 8 - They are moving very fast and are far apart -
Note that the closer together molecules are together, the harder something is :D

Boyle’s Law states that, when temperature is held constant, the pressure and volume of a gas are inversely proportional.
Gas laws are defined as the laws that govern the properties of gases by determining the relationships between the pressure, volume and temperature of the gases.
Here,
Boyle's law is the gas law that governs the relationship between the pressure and volume of gases.
Boyle's law states that, for an ideal gas at a unit mass, the pressure of the gas is inversely proportional to the volume of the gas, at constant temperature.
P 1/V
PV = a constant
When the temperature of the gas is held constant.
Hence,
Boyle’s Law states that, when temperature is held constant, the pressure and volume of a gas are inversely proportional.

Answer:
When temperature is held constant, the pressure and volume of a gas are not proportional.
Explanation:
That is Boyle's Law
Answer: Increase internal energy and work done by the system
Explanation: According to the first law of thermodynamics conservation of energy, when heat is added to the system then the system gain or loss of energy.
So, when we add heat to a system then increases internal energy and external work done by the system.
temperature rises ? specific heat capacity etc ...
