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.
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.
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Heat energy is measured in joules (newton-meters), which are also a unit of work.The calorie is a mostly-superseded unit equal to 4.2 joules, while the "food energy" calorie is actually a kilocalorie (1000 calories).Units of temperature are a related value, indicating the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.

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 much energy would you use to raise temperature of kg of water by 2 degrees Celsius?
The amount of energy required to raise the temperature of 1 kg of water by 1 degree Celsius is approximately 4,186 Joules. Therefore, to raise the temperature by 2 degrees Celsius, you would need about 8,372 Joules of energy.
How much heat in joules would you need to raise the temperature of 1kg of water by 5 and degC?
You would need 20,920 Joules of heat to raise the temperature of 1kg of water by 5°C. This value is calculated using the specific heat capacity of water, which is 4186 J/kg°C.
How many joules are required to boil one liter of water?
It takes approximately 4186 joules to raise the temperature of one liter of water to its boiling point and an additional 2260 joules to convert it from liquid to vapor. So, in total, around 6446 joules are required to boil one liter of water at normal atmospheric pressure.
How many joules does it take to raise temperature from 30 degrees Celsius to 45 degrees Celsius?
To raise the temperature of a substance, you need to calculate the heat energy using the specific heat capacity of the substance. Without knowing the specific heat capacity of the substance in question, it's not possible to determine the exact amount of energy required to raise the temperature from 30 to 45 degrees Celsius.
What is the amount of energy needed to raise the temperature of 1 gram of water by 1 degrees Celsius?
The specific heat capacity of water is 4.18 Joules/gram degrees Celsius. Therefore, it would take 4.18 Joules of energy to raise the temperature of 1 gram of water by 1 degree Celsius.
How many joules does it take to warm water by 1 degree?
It takes 4186 joules to raise the temperature of 1 kilogram of water by 1 degree Celsius. The mass does make a difference.
How much energy is required to raise water temp 1 degree Celsius?
The amount of energy required to raise the temperature of water by 1 degree Celsius is known as its specific heat capacity. For water, the specific heat capacity is 4.18 Joules/gram°C. This means that it takes 4.18 Joules of energy to raise the temperature of 1 gram of water by 1 degree Celsius.
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
Why do you use a match to light an alcohol lamp?
we use a match to raise the temperature of the alcohol that the wick absorbed
How many joules of heat are necessary to raise temperature of 125g of copper from 25 degrees celsius to 300degrees celsius?
The answer is 53,683 kJ.
How specific heat different from heat capacity?
Specific heat capacity is the amount of energy required to raise the temperature of one unit mass of a substance by one degree Kelvin. Eg. The specific heat capacity of water is 4.18 joules per gram. So you need to transfer 4.18 joules of energy to one gram of water in order to raise it by one degree K Temperature on the other hand is the average kinetic energy of the particles in a substance.
