Energy is actually given off in the lowering of temperature. Use the equation Q = mc(change in T). In this case, m = 2.9, c = 4.179 J, and change in T = -12.1 degree C. Now solve for Q, the heat energy. This exothermic process gives off approximately 146.6 J of heat.
Heat energy is typically measured in joules (J) or calories (cal). Degrees Celsius and degrees Fahrenheit are units of temperature, not energy.
Heat itself is not measured in degrees Celsius; rather, temperature is measured in degrees Celsius. Heat is a form of energy that is transferred between objects or systems due to a temperature difference. The SI unit for heat energy is the joule (J), while the SI unit for temperature is the degree Celsius (°C).
The specific heat capacity of steam at 100 degrees Celsius is approximately 2.08 J/g°C. This means it takes 2.08 joules of energy to raise the temperature of 1 gram of steam by 1 degree Celsius at that temperature.
The heat lost by 1 gram of water at 0 degrees Celsius as it freezes to form ice is approximately 333.55 joules. This is the heat of fusion of water, which is the energy required to change the state of water from a liquid to a solid at its melting point.
To calculate the heat lost, you need to use the formula: Q = mcΔT where: Q = heat lost m = mass of granite (3580 kg) c = specific heat capacity of granite (approx. 790 J/kg°C) ΔT = change in temperature (41.2 - (-12.9) = 54.1°C) Plug in the values and calculate to find the heat lost in joules.
The answer is 53,683 kJ.
8.200 J
False. Heat is measured in units of energy such as calories or joules, not in degrees Celsius. Temperature, on the other hand, is measured in degrees Celsius.

Approx 4974 Joules.

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.
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.
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.
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.
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 ===========================
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.
