1 joule = 2.39 X 10-4 kcal
65-30 = 35 degrees
1 kcal = 1 degree kg
35 degrees X 0.5 kg / 2.39 X 10-4 kcal/joulle = 73222 joules

How many joules are absorbed by the water with a mass of 8 kg in order to raise the temperature from 20 degrees to 70 degrees?
q(joules) = mass * specific heat * change in temperature ( 8 kg = 8000 grams ) q = (8000 grams H2O)(4.180 J/gC)(70o C - 20o C) = 1.7 X 106 joules ============
What is the quantity of heat in joules needed to raise the temperature of 40.0g of Al from 25 degrees Celsius to 50 degrees Celsius?
E = mass x specific heat x Δ°T Δ°T = new temperature - original temperature where Δ°T is equal to temperature change (Celsius in this case). The specific heat of Al is 0.900 J/g°C. Before we proceed to find the quantity of heat in joules, we must first find the temperature change. To calculate the temperature change, we must subtract the original temperature from the new temperature. Δ°T = 50°C - 25°C = 25°C In order to find the quantity of heat (joules), we must multiply mass, specific heat, and the temperature change (calculated above). E = 40.0g x 0.900 J/g°C x 25°C = 900 Joules or 9.0 x 102 Joules
How much energy does it take to heat 1 kg of water from 33 deg F to 34 deg F?
The energy required to raise the temperature of water depends on the atmospheric pressure as well as the starting temperature. At a pressure of one atmosphere, the amount of energy required to raise the temperature of water from 0 deg C to 100 deg C (32 to 212 deg F) is 4.19 joules per gram. At 4 deg C, (39.2 deg F) it is approx 4.204 joules per gram per deg C. That is 4.204/1.8 = 2.33555... recurring joules per gram per deg F and so, for a kilogram, the energy required is 2335.55... joules.
What units would you use to measure heat?
Heat energy is measured in joules (newton-meters), which are also a unit of work.The calorie is a mostly-superseded unit equal to 4.2 joules, while the "food energy" calorie is actually a kilocalorie (1000 calories).Units of temperature are a related value, indicating the relative contained heat energy. The units of temperature are the kelvin / degree Celsius and the different interval, the degree Fahrenheit. Classically, adding 1 mean calorie of heat energy would raise the temperature of 1 gram of water by 1 degree Celsius.
Specific heat of air?
The specific heat of air at 0 degrees Celsius is 1.01 Joules per gram or J/g. The specific heat of a substance is defined as the quantity of heat per unit mass needed to raise its temperature by one degree Celsius.
How many joules are absorbed by the water with a mass of 8 kg in order to raise the temperature from 20 degrees to 70 degrees?
q(joules) = mass * specific heat * change in temperature ( 8 kg = 8000 grams ) q = (8000 grams H2O)(4.180 J/gC)(70o C - 20o C) = 1.7 X 106 joules ============

How many joules of energy are required to raise the temperature of 150.0g of water from 274K to 318K?
4.184 J/g/K = 4.184 x 150 x (318-274) = 27614 Joules
Explain how the specific heat of a substance is determined?
specific heat is the amount of heat to be absorbed required to raise a substance 1 degree celsius. And by heat being absorbed, i mean energy, because specific heat is measured in joules
