Answer: 18634 joules
Explanation:
The quantity of Heat Energy (Q) released when a heated substance is cooled depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)
Thus, Q = MCΦ
Since,
Q = ?
Mass of oil = 345g
C = 0.220 J/g°C
Φ = (Final temperature - Initial temperature)
= 0°C - 220°C = -220°C
Then, Q = MCΦ
Q = 345g x 0.220 J/g°C x -220°C
Q = 18634 joules (note that negative sign will not reflect in answer, because it only indicates that heat was released rather than gained)
Thus, 18634 joules of heat is released
Answer: carbon dioxide water and sunlight
Answer:
1. All the possible energy transformations that occur with a dishwasher that uses electrical energy are heat energy because the dishwasher uses the electrical energy to heat the water, also electrical energy is transformed into kinetic energy and sound energy the reasoning behind this is that the parts moving inside the dishwasher is causing the sound.
2. Take as an example a light bulb inside a lamp to illuminate a room. When you plug it in a plug and turn it on, light is generated. More precisely, heat (Joule effect) is produced inside the lamp by its internal filament (conductive material) when it passes through the electrical energy, generated by the friction of the atoms that are inside it when it encounters a resistance.
