8. Calculate the amount of heat (in kJ) required to heat 1.01 kilogram of water from 5°C to 35.81°C. [Specific heat of water-4.184J/g.°C] A metal ball with a mass of 100.0 g was heated to a temperature of 88.4°C and then dropped into 125 g water originally at 25.1°C. The final temperature of both the metal ball and the water is 31.3°C. Calculate the specific heat capacity (s) of the metal. [Specific heat capacity of water = 4.184J/g.°c).
Calculate the amount of heat necessary to raise the temperature of 135.0g of water from 50.4 degrees F to 85 degrees F. The specific heat of water is=4.184J/g.degrees C.
Calculate the amount of heat that must be absorbed by 100.0 g of water at 20.0°C to convert it to steam (water vapor) at 110.0°C. Given: Specific heats: (liq) = 4.18 J/g·°C (steam) = 1.84 J/g·°C DHvap = 40.7 kJ/mol
A 66.52-g sample of water is heated from 71.33 °C to 80.96 °C. Calculate the energy absorbed by the water in joules. The specific heat of water is 4.20 J/g" in this temperature range. Do not type the units with your answer and use standard notation (not scientific). Type your answer.
The quantity of heat absorbed by 16.5 g of water (Specific heat of water = 1.0 cal/g0c) heated from 210C to 390C. (Specific heat of water = 1cal/g0c) A. 3.0x102 cals B. 3.2x102cals C. 3.4x102cals D. 3.20x102cals
please help When a solid dissolves in water, heat may be evolved or absorbed. The heat of dissolution (dissolving) can be determined using a coffee cup calorimeter. In the laboratory a general chemistry student finds that when 0.85 g of CaCl2(s) are dissolved in 100.10 g of water, the temperature of the solution increases from 24.36 to 25.89 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be...
A 50g sample of iron is heated to 75.2°C and placed into a calorimeter holding 70g of water at a temperature of 25°C. Assuming no heat loss to the calorimeter, what will be the final temperature reached in the calorimeter? Specific heat capacity of iron = .444J/g•C° Specific heat capacity of water = 4.184J/g•C°
Calculate the amount of energy needed to heat 346 g of liquid water from 0°C to 182°C. Assume that the specific heat of water is 4.184 J g-1 °C-1 over the entire liquid range and that the specific heat of steam is 1.99 J g-1 °C-1 ; ΔvapH (H2O) = 40.8 kJ mol-1 Please show your method. Thank you!
a. When a solid dissolves in water, heat may be evolved or absorbed. The heat of dissolution (dissolving) can be determined using a coffee cup calorimeter. In the laboratory a general chemistry student finds that when 16.11 g of BaCl2(s) are dissolved in 118.70 g of water, the temperature of the solution increases from 22.98 to 25.41 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.71...
