Explanation:
activation energy, in chemistry, is the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo a chemical transformation or physical transport.
Since the container of the gas is rigid, the volume of the gas will remain constant. Therefore, when the number of particles were decreased in half then the pressure will also be half of the original given they both are subjected to the same temperature.
PV = nRT
V, T and R are constants so they can be lumped together to a constant k.
P/n = k
P1/n1 = P2/n2
since n2 = n1/2
P1/n1 = P2/<span>n1/2</span>
P2 = P1/2
Answer:
- <em>Sample X</em>, contains the most heat.
Explanation:
In thermodynamics, the <em>heat content</em> of heat of a system or a substance is described by the term enthalpy.
The heat content (enthalpy) is an extensive property, meaning that it is dependent on the amount of substance.
More substance more heat energy content.
Heat content is also related with the temperature. The higher the temperature the greater the kinetic energy and the higher the heat content.
Since, sample X and sample Y are both at the same temperature of 42°C, this variable does not differentiate the heat content of such samples.
Since, the sample X has more volume than sample Y, as per the previous conclusion that the more substance the more heat energy, you can certainly asses that the former contains the most heat.

Answer:
Amplitude is measured from the center line to the highest point in the waves.
Wavelength is the distance between one wave to the other from the highest point.
Frequency is the rate of the waves.
