If the heat necessary to warm 530.0 g of water from a temperature of T1 = 20.0 °C to T2 = 87.0 °C were somehow converted to translational kinetic energy of this amount of water, what would be the speed of this water?
(a) How much energy is necessary to heat 4.0 kg of water from room temperature (20°C) to its boiling point? (Assume no energy loss.) (b) If electrical energy were used, how much would this cost at 23¢ per kWh?
Assuming that radiation with a wavelength = 15.0 cm is used, that all the energy is converted to heat, and that 4.184 J is needed to raise the temperature of 1.00 g of water by 1.00 degree celcius, how many photons are necessary to raise the temperature of a 350 mL cup of water from 25 degree C to 95 degree C?
For an ideal gas, whose temperature increases from T1 to T2, what would be its enthalpy change? (a) Cv (T2-T1) (b) Cv (T1-T2) (c) Cp (T2-T1) if the heat capacities stay constant during the temperature range
Part A Find the amount of heat that must be extracted from 1.0kg of steam at 150?C to convert it to ice at 0.0 ?C. Part B What speed would this 1.0-kg block of ice have if its translational kinetic energy were equal to the thermal energy calculated in part A?
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.
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...
We did the lab of latent heat of fusion of ice, and I am confused that what the 'water equivalent' represents. I thought it is the amount (kg) of water, but it is mccc according to this lab manual, which unit is (J/oC). Please answer what the water equivalent represents and the unit of it. - In this experiment, an ice cube of mass mt, assumed to be at 0°C, is placed in a calorimeter containing a mass of water...
The specific heat of a substance varies with temperature according to the function c = A + BT + CT 2. Find the energy required to raise the temperature of a mass m of this substance from T1 and T2. (Use any variable or symbol stated above as necessary.)
How much heat, in J (Joules), is required to warm 32.1 g of water from 20.1 ∘C to 63.1 ∘C?
