How many kilocalories are needed to raise the temperature of 10.5 kg of steam from 120oC to 150oC?arrow_forward1-55 Does the chemical nature of a substance change when it melts from a solid to a liquid?arrow_forward
- Which is the higher temperature, 15C or 4F?arrow_forward1-86 The specific heats of some elements at 25oC are as follows: aluminum = 0.215 cal/g · oC; carbon (graphite) = 0.170 caI/g oC; iron = 0.107 cal/g mercury = 0.033 1 caI/g oC. (a) Which element would require the smallest amount of heat to raise the temperature of 100 g of the element by 10oC? (b) If the same amount of heat needed to raise the temperature of 1 g of aluminum by 25oC were applied to 1 g of mercury, by how many degrees would its temperature be raised?
