Answer: -112200J
Explanation:
The amount of heat (Q) released from an heated substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)
Thus, Q = MCΦ
Since,
Q = ?
Mass of water vapour = 30.0g
C = 187 J/ G°C
Φ = (Final temperature - Initial temperature)
= 100°C - 120°C = -20°C
Then apply the formula, Q = MCΦ
Q = 30.0g x 187 J/ G°C x -20°C
Q = -112200J (The negative sign does indicates that heat was released to the surroundings)
Thus, -112200 joules of heat is released when cooling the superheated vapour.
Solar sunspot activity affected global climate during the Maunder Minimum by make the global climate much colder due to low sunspots.
hope this helps :)
Because as each organism goes up, there's less energy being given. Here's an example.
Take a plant, it has 100% of its energy. Then it's eaten by a deer, which could be the Primary Consumer. The deer has 10% of the beginning energy. Then, the deer is eaten by a wolf, a Secondary Consumer, which then has 1% of the energy.
