2.50 L of gas originally at 50 K is warmed to 80 K. If the pressure remains constant, which gas law needs to be used to find the
Brilliant_brown [7]

Answer:

A

Explanation:

You want an equation that includes both V and T. Charles' Law states that V =kT or V₁/T₁ = V₂/T₂, so this is the best formula to use.

B: The Combined Gas Law is p₁V₁/T₂ = p₂V₂/T₂ will work, but it's overkill for the situation. You can assume any constant value for the pressure, and it will cancel from each side of the equation,

C is wrong. Boyle's Law is p₁V₁ = p₂V₂. It does not include the temperature.

D is wrong. Gay-Lussac's Law is p₁/T₂ = p₂/T₂. It does not include the volume.

Nonrenewable energy sources _____.
shusha [124]

Non-renewable energy sources CAN EVENTUALLY BE USED UP.

Non renewable energy sources refer to those energy sources that can not be replenished. Once they are used up, new one can not be formed or produced, this is because they can only be formed by natural processes and these processes take millions of years to occur. Examples of non renewable energy sources are: coal, natural gas and oil. All the fuels obtained from fossils are non renewable in nature.

Dylan puts two magnetic toy trains very close to each other on a track. What will happen next, and why?
guajiro [1.7K]
If the magnetic toy trains are opposite charges, they will attract each other and collide however if the trains are of the same charge, they will oppose each other. This is because electrostatic force (the opposite forces so + and -) attract opposite charges

Hope that helps :)
