The same amount of heat entering identical masses of different substances produces different temperature changes. Calculate the final temperature when 1.45 kcal of heat enters 1.13 kg of the following, originally at 24.2°C. The specific heat capacity for each material is given in square brackets below. (a) water [1.00 kcal/(kg · °C)] °C (b) concrete [0.20 kcal/(kg · °C)] °C (c) steel [0.108 kcal/(kg · °C)] °C (d) mercury [0.0333 kcal/(kg · °C)] °C
Calculate the final temperature when 1.5 kcal of heat transfers into 2.3 kg of mercury originally at 23.7ºC. The specific heat of mercury is 0.0333 kcal/kgºC .
If 30 g of gold (of specific heat 0.0.03 kcal/kg ∙ °C) at 110°C is put into 75 g of water (of specific heat 1.0 kcal/kg ∙ °C) at 0°C. What is the final temperature of the mixture?
How much heat is required to raise the temperature of a 2.0 kg of water (specific heat = 1.0 cal/g°C) from 15.0°C to 100.0°C?
Specific heat is the heat necessary to raise the temperature of 1kg of a given material by 1∘C. This specific heat value varies by material with metals having relatively low specific heat with organic materials and water being very high. The specific heat of mercury is 140 J/kg∘C and the specific heat of water is 4190 J/kg∘C. 1.140 J of heat energy are transferred to 30.9 g of mercury. By how much does the temperature increase in Celsius? 2. How...
How much heat in kcal must be added to 0.31 kg of water at room temperature (20°C) to raise its temperature to 32°C?
