For an approximate calculation:
specific heat capacity for water = 4.18 J/(g*degC)
(how much energy is required per gram per change in degrees C)
mass = 25g
Change in temperature = 60-10 = 50 degC
energy required = mass * change in temperature * specific heat capacity
= 25g * 50 degC * 4.18 J/(g*degC)

The specific heat capacity of water is 4.18 J/g°C. The heat required can be calculated using the formula: Q = m x c x ∆T, where Q is the heat energy, m is the mass of water, c is the specific heat capacity of water, and ∆T is the change in temperature. Plugging in the values, we get: Q = 25 g x 4.18 J/g°C x (60°C - 10°C) = 4180 J. So, 4180 Joules of heat are required.

∙ 14y agoSpecific Heat capacity( S) is the amount of heat required to raise the temperature of unit mass of substance through 10C.
Let H be heat supplied, T be temperature change, m be mass of body.
Now as per our definition
Specific Heat capacity = heat supplied/mass of body*temperature change
or S = H/T*m
Putting values into the formula we have:
S = 26kJ/250g*1670C
S = 26000J/(1/4 kg * 1670C)
S = 622.75 J/kg* 0C
Hence Specific Heat capacity of substance = 622.75 J/kg* 0C.
This is done by assuming no phase change occurs during heating and substance remained in the same state as on beginning.

How much heat energy would be required to bring a 15 kg block of ice from -20 degrees Celsius to steam at 120 degrees Celsius?
To bring the ice block to 0 degrees Celsius, you would need 150,000 Joules (Q = mcΔT). To melt the ice at 0 degrees Celsius, you would need 3,375,000 Joules (Q = mLf). Heating the water from 0 to 100 degrees Celsius would require 1,500,000 Joules (Q = mcΔT). Turning the water to steam at 100 degrees Celsius would need 10,500,000 Joules (Q = mLv). Finally, heating the steam to 120 degrees Celsius would require 600,000 Joules (Q = mcΔT). In total, you would need 15,125,000 Joules of heat energy.
How much heat energy is needed to convert 50 kg of water at 80 degrees Celsius to steam at 100 degrees Celsius?
To convert 50 kg of water at 80 degrees Celsius to steam at 100 degrees Celsius, you need to calculate the heat energy needed to raise the temperature of water from 80 to 100 degrees Celsius (specific heat capacity of water) and then the heat energy needed for water to steam phase change (latent heat of vaporization of water). The total heat energy required can be calculated using the formula: Q = mcΔT + mL, where Q is the heat energy, m is the mass, c is the specific heat capacity, ΔT is the temperature change, and L is the latent heat of vaporization.
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.
How many calories are needed to raise the temp of 8.1 g of water 20 degrees Celsius?
The specific heat capacity of water is 4.18 J/g°C, which means it takes 4.18 Joules of energy to raise 1 gram of water by 1 degree Celsius. To raise the temperature of 8.1 g of water by 20 degrees Celsius, you would need 8.1 g * 20°C * 4.18 J/g°C = 676.56 Joules of energy.
What is the specific heat of solid uranium?
The specific heat of solid uranium is approximately 0.116 joules/gram degrees Celsius. It is a measure of the amount of heat required to raise the temperature of a unit mass of the substance by one degree Celsius.

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 specific heat of ice at 0 degrees celsius?
The specific heat of ice at 0 degrees Celsius is approximately 2.09 Joules/gram degree Celsius. This means that it takes 2.09 Joules of energy to raise the temperature of 1 gram of ice by 1 degree Celsius.
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 ===========================
Is heat measured in celsius degrees?
No, heat is a form of energy and is typically measured in joules or calories. Temperature, on the other hand, is measured in degrees Celsius or Fahrenheit and is a measure of the average kinetic energy of particles in a substance.
