Temperature is a measure of _____.
2 answers:
Answer: Option (b) is the correct answer.
Explanation:
Movement of molecules of a substance is dependent on temperature also. This is because energy obtained by an object due to its motion is known as kinetic energy.
Also,
Hence, kinetic energy is directly proportional to temperature which means that when there is increase in temperature then there will occur an increase in molecular movement of the substance.
Similarly, a decrease in temperature will lead to a decrease in molecular movement of the substance.
Thus, we can conclude that temperature is a measure of molecular movement .

Answer:
134.75935 seconds
Explanation:
m = Amount of water = 240 mL
c = Specific heat of water = 4.2 J/mL °C
= Change in temperature =
t = Time taken
P = Power = 1100 W
E = Pt
Efficiency = 51 %
So, Energy = 0.51Pt
As energy is conserved
Q = 0
The it takes to raise the temperature is 134.75935 seconds
