How many kilo joules of energy are released when 1.60 kg of water cools from 80.0 degrees Celsius to 60.0 degrees Celsius?
The specific heat capacity of water is 4.18 J/g°C. First, calculate the heat energy required to cool the water from 80.0°C to 60.0°C using the formula: q = mcΔT, where q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the temperature change. Then, convert the heat energy from joules to kilojoules.

Heat is measured in Celsius degrees true or false?
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.
How much heat is released when 1000g of steam at 100 degrees Celsius condenses?
When steam at 100 degrees Celsius condenses, it releases 2260 Joules of energy per gram. Therefore, for 1000g of steam, the heat released would be 2,260,000 Joules (2260 J/g * 1000 g).
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 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.
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.
Is heat energy measured in units of joules degrees Celsius and in degrees Fahrenheit?
Heat energy is typically measured in joules (J) or calories (cal). Degrees Celsius and degrees Fahrenheit are units of temperature, not energy.
Heat is measured in Celsius degrees true or false?
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.
How much heat is released when 1000g of steam at 100 degrees Celsius condenses?
When steam at 100 degrees Celsius condenses, it releases 2260 Joules of energy per gram. Therefore, for 1000g of steam, the heat released would be 2,260,000 Joules (2260 J/g * 1000 g).
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.

Is heat is measured in degrees Celsius?
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).
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.
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.
Does it it take more energy to heat the water to 100 degrees celsius or boil it?
If by "boil" you mean have it all evaporate, that takes MUCH more energy. For example, to increase the temperature of one gram of water from 20 to 100 degrees Celsius, you need 4.2 joules/gram/degree times 80 degrees = about 336 joules; then, to evaporate all the water, you need an additional 2257 joules.
How much heat is released when 12.4 g of steam at 100 degrees celsius condenses to water at 100 degrees celsius?
The latent heat of condensation of steam is 2260 Joules per gram (539.3 cals/g). So the amount of heat released by 12.4 g = 12.4*2260 Joules = 28,024 Joules or 6687 cals.
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.
