Answer:
chemical energy is stored in the wood before combustion.
Answer:
Explanation:B ice melting is a phiyscal change and the mass of the substance remains the same
Answer: 14943.5 J
Explanation:
The quantity of heat energy (Q) required to raise the temperature of a substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)
Thus, Q = MCΦ
Given that,
Q = ?
Mass of water = 55.0g
C = 4.18 J/g°C
Φ = 65.0°C
Then, Q = MCΦ
Q = 55.0g x 4.18 J/g°C x 65.0°C
Q = 14943.5 J
Thus, 14943.5 joules of heat is needed to raise the temperature of water.
Answer:
Evaporation
Explanation:
Evaporation is the certain process that requires water to gain heat energy from the environment.
Answer:because it isnt flammable
