If you were to burn a candle under equal masses of water and iron for the same amount of time, would one increase in temperature more than the other? which one?
Iron takes less heat to change temperature,it has lower specific heat content.
To determine which material, water or iron, would experience a greater increase in temperature when a candle is burned under them for the same amount of time, we need to consider their specific heat capacities.
The specific heat capacity is the amount of heat energy required to raise the temperature of a substance by a certain amount. Water has a higher specific heat capacity compared to iron.
This means that for the same mass, it takes a larger amount of heat energy to raise the temperature of water compared to iron. Therefore, when the candle burns, more of the heat energy will be absorbed by the water than by the iron for the same amount of time.
As a result, the water will experience a greater increase in temperature than the iron when the candle burns under both materials for the same amount of time.
