The same heat transfer into identical masses of different substances produces different temperature changes. Calculate the final temperature in degrees Celsius when 1.25 kcal of heat enters 1.25 kg of the following, originally at 15.0°C.
(a)water °C
(b)concrete°C
(c)steel °C
(d) mercury °C
Alright Dude, If that worked for you... dont forget to give THUMBS UP.(that will work for me!)
If I missed something feel free to leave a comment.
atleast before giving downvote.

The same heat transfer into identical masses of different substances produces different temperature changes. Calculate the final temperature in degrees Celsius when 1.50 kcal of heat enters 1.00 kg of the following, originally at 17.5°C. (a) water (b) concrete (c) steel (d) mercury
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 .
Calculate the final temperature of the water from the following heat transfer experiment. 45 g of water at an initial temperature of 36 degree C (Celsius) is added to 100.0 g of water at 100.0 degree C. The experiment is performed in an insulated container to prevent heat loss to the surroundings. Specific heat of water = 4.184 J/(g degree C) State your answers in degrees Celsius (C) with 3 significant figures.
please answer all questions Temperature Change and Heat Capacity - Calorimetry- Two substances The quantitative relationship between heat transfer and temperature change is Q = mcAT, where Q is heat transfer, m is the mass of the substance, and AT is the change in temperature. The symbol c stands for specific heat and depends on the material and phase. The specific heat c is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00°C....

2. Heat flow, temperature changes, and changes of phase You have a furnace (Tfurnace 400° C that effectively provides an infinite heat source. You design a steel rod (k 50.2 W/m K) that can transmit heat from the furnace to need to a pot of water (specific heat, c = 4190 J/kg.K to raise it's temperature to 100° C. Suppose 1 kg of water in the pot, and the water is initially at a temperature that you have m 10°...
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...
