How many kilojoules of energy are necessary to raise the temperature of 3 kilograms of cast iron from 30 degrees celsius to 120 degrees celsius?
I will use this formula. Some conversion will be required. ( I only know specific heat iron in J/gC )
q(Joules) = mass * specific heat * change in temperature Celsius
3 kilograms cast iron = 3000 grams
q = (3000 g)(0.46 J/gC)(120 C - 30 C)
= 124200 Joules (1 kilojoule/1000 joules)
= 124.2 kilojoules of energy needed

What is the specific heat capacity of air in kilojoules per kilogram degree Celsius?
The specific heat capacity of air is approximately 1.005 kilojoules per kilogram degree Celsius.
How do you convert 2.35 kilojoules of heat to degree celsius?
To convert 2.35 kilojoules of heat to degrees Celsius, you need to know the specific heat capacity of the substance being heated. Once you have this value, you can use the formula: Heat energy (in joules) = mass * specific heat capacity * change in temperature. By rearranging the formula, you can calculate the change in temperature in degrees Celsius.

19 050 kilograms
How do you convert celcius ito kelvin?
To convert Celsius to Kelvin, you add 273.15 to the Celsius temperature. The formula is: K = °C + 273.15, where K is the temperature in Kelvin and °C is the temperature in Celsius. This conversion is necessary because Kelvin is an absolute temperature scale that starts at absolute zero.
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 many kilo joules are need to raise the temperature 17 Celsius to 34 Celsius?
To calculate the energy required, you can use the formula: Q = mcΔT Where Q is the energy in joules, m is the mass in grams, c is the specific heat capacity, and ΔT is the change in temperature in Celsius. Given the temperature change is from 17°C to 34°C and you have the mass and specific heat capacity, you can calculate the energy required in kilojoules.
What is body core temperature in celsius?
Body core temperature in Celsius is typically around 37 degrees. This temperature is necessary for normal bodily functions and is regulated by the hypothalamus in the brain. Changes in core temperature can indicate illness or other medical conditions.
Is Celsius the opposite of temperature?
No, Celsius is a unit of temperature measurement on the Celsius scale. It is not the opposite of temperature, but a way to quantify it.
What is the average room temperature in kilograms?
The kilogram (kg) is a unit of mass, and cannot be applied to temperature. However, room temperature is generally regarded as 20 degrees Celsius, which is 68 degrees Fahrenheit, or 293 kelvins.
