Answer:
By adding heat energy
It changed to gas
Explanation:
A substance whose molecules are moving around each other is a liquid. They are held in shape by very weak intermolecular forces.
For solids, there is no movement because the molecules are held up in a fixed lattice.
Gases molecules moves randomly and independently of one another.
- When a liquid is heated and it gains heat energy, it changes phase.
- A phase change to gas can be predicted.
- This is because there is an increase in the speed of the substances.
Answer:
113.8 J.
Explanation:
The following data were obtained from the question:
Mass (M) = 8.2 g
Change in temperature (ΔT) = 3.32 °C
Specific heat capacity (C) = 4.18 J/gºC
Heat required (Q) =..?
The heat required to raise the temperature of the water by 3.32 °C
can be obtained as follow:
Q = MCΔT
Q = 8.2 × 4.18 × 3.32
Q = 113.8 J
Therefore, the amount of heat required to raise the temperature of the water is 113.8 J.
