How much he is required to convert 3 kg gram of ice at zero Celsius to water at the same temperature?
To convert 3 kg of ice at 0 degrees Celsius to water at the same temperature, you would need to supply 3,360,000 joules of heat (latent heat of fusion of ice is 334,000 J/kg). This energy will help melt the ice into water at 0 degrees Celsius.
A particular sample of iron requires 562 Joules to raise its temperature from 25 degreee Celsius to 50 degrees Celsius. What must be the mass of the sample of iron?
The change in temperature is 25 degrees Celsius, meaning it takes 22.48 joules per degree of change. The specific heat of iron is 0.449 J/g degree Celsius. This means that the mass of iron must be 50.07 grams
Specific heat capacity of castor oil?
The distillation point, or the point at which the oil burns, is at 295 degrees Celsius. This process is used to purify the oil.
What is the unit measure for specific heat?
specific heat is in the units Joules/(gram x oC)AnswerThe correct term is 'specific heat capacity', and it is measured in joules per kilogram kelvin (J/kg.K)
What process requires water to gain 2260 joules energy per gram?
The process that requires water to gain 2260 joules of energy per gram is known as specific heat capacity. Water has a specific heat capacity of 4.18 J/g°C, which means it takes 4.18 joules of energy to raise the temperature of 1 gram of water by 1 degree Celsius.
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 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 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.
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 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 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.
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 ===========================
