Collisions of helium atoms with the walls of a closed container causea. condensation.
b. gas pressure.
c. a decrease in volume.
d. an overall loss of energy.
Raising the temperature of a gas will increase its pressure if the volume of the gas
a. and the number of particles are increased.
b. is increased, but the number of particles is constant.
c. and the number of particles are constant.
d. is constant, but the number of particles is reduced.
Answers
This is sustainted by the kinetic molecular theory of the gases.
2) Option c: raising the temperature of the gas will increase the pressure if the volumen of the gas and the number of particles are constant.
PV = nRT
If V and n are constant, P is proportional to T, then if T increase P will increase too.
In less scientific words
For number 1 is GAS PRESSURE
And number 2 is TEMPERATURE
- I hope this works for you guys

Using Einstein’s famous equation, E = mc^2
Given mass, m = 0.112 kg and knowing c = 3.0 x 10^8 m/s, energy E can be determined
E = (0.112 kg)(3.0 x 10^8 m/s)^2
= 1.008 x 10^16 J
Hope this helps
Answer:
Joules is the energy equivalent of this .
Explanation:
Mass of hydrogen atoms in 1 kg of water = 112 g= 0.112 kg
Mass and energy related together and that expression was given by the famous scientist named Albert Einstein:
E = Energy related to mass m
c = Speed of the light
m = 0.112 kg , c =
Joules is the energy equivalent of this .
