Answer:
Gases consist of particles (molecules or atoms) that are in constant random motion. ... The average kinetic energy of gas particles is proportional to the absolute temperature of the gas, and all gases at the same temperature have the same average kinetic energy.
Answer:
Explanation:
Q = m × Cp × delta T
Where,
Q is the heat gained by water
m is the mass of water
Cp = specific heat capacity of water
= 4.18 kJ per kilogram per degree Celsius (J/kg°C).
This means that it takes 4,180 J to raise the temperature of 1 kg of water by 1°C
delta T is the difference in temperature
A.
The smaller beaker had a bigger temperature rise because the same energy has been given to a smaller number of water particles in the beaker than those particles in the large beaker so each particle is moving faster than those in the other beaker.
B.
Since both beakers were heated at the same time, they both gain the same amount of energy.
Qlarge = Qsmall
Answer:
Brittle.
