To calculate the energy required to heat 3 kg of water from 0°C to 100°C, you can use the formula: ( Q = mc\Delta T ), where ( Q ) is the heat energy, ( m ) is the mass of the water (3 kg), ( c ) is the specific heat capacity of water (approximately 4,186 J/kg°C), and ( \Delta T ) is the change in temperature (100°C - 0°C = 100°C).
Plugging in the values:
( Q = 3 , \text{kg} \times 4,186 , \text{J/kg°C} \times 100 , \text{°C} = 1,255,800 , \text{J} ).
So, it will take approximately 1,256,000 joules (or 1.256 MJ) of energy.
Heat because Ice and water would thaw out and begin to heat up
Gold takes less heat energy than water to change temperature due to its lower specific heat capacity. Specific heat capacity is the amount of heat required to raise the temperature of a substance by one degree Celsius. Water has a high specific heat capacity, meaning it can absorb more heat without a significant temperature change, while gold, being a metal, has a much lower capacity, allowing it to heat up or cool down more quickly with less energy input.
The specific heat of a substance allows us to calculate the amount of heat energy required to change its temperature. Water has a specific heat nearly 11 times great than copper, therefore, water will take 11 times more energy to heat. Also water heats slowly and copper heats and cools rapidly.
To calculate the amount of heat required to raise the temperature of water, you can use the formula: Q = mcΔT, where Q is the heat energy, m is the mass of water (645g), c is the specific heat capacity of water (4.184 J/g°C), and ΔT is the change in temperature (25°C). Plugging in these values, you will find the amount of heat needed in joules.
To calculate the energy required to raise the temperature of water, you can use the formula: energy = mass x specific heat capacity x temperature change. The specific heat capacity of water is approximately 4.18 J/g°C. Plugging in the values, the energy required would be 10.0 g x 4.18 J/g°C x 25.0°C = 1045 Joules.
The specific heat of water determines how much energy is needed to heat water.
Heat because Ice and water would thaw out and begin to heat up
It depends on which temperature you want to reach and at which temperature is the water before you start heating it!
If you take energy in the form of heat, from water it will freeze and so is not water any more.
geothermal energy, why? because geothermal energy runs off of the earths heat and does not take heat away from the earth it will never stop giving of energy win or no wind rain or no rain water or no water
A calorie of energy (NOT to be confused with a Calorie, they are different so watch the caps) is the amount necessary to heat 1 gram of water 1oC, so 30 calories are needed to heat 30 g of water 1 degree. To heat it 70oC would take 2100 calories (or 2.1 Calories) of energy.
Ok, lets assume that a pool of water and the air are at the same temperature. There are a number of ways you can lose heat to the surroundings, however in this example the most important reason is: Conduction. This is due to direct contact with surrounding particles. As the Particles in you body vibrate with energy they collide with surrounding air or water particles. You will thus lose much more energy to water than to air as water is much better at conducting heat away from you. (There are many times more water particles to transfer the energy away). In terms of heat capacity, if water has a higher heat capacity then it will take more energy from your body to heat it up. Seeing as you body is warmer than the surrounding water, the water will take more of your thermal energy to reach thermal equilibrium with you.
A solution can take in energy, which is heat.
To heat 1 gram of water by 1 degree Celsius, it takes 4.18 joules. So, to heat water from, for example, 20 degrees to 100 degrees, you would need to calculate the total mass of water and apply the specific heat capacity to determine the total energy required.
It must flow out, ice contains less energy than water. You just have to remember that heat is energy, and all energy, no matter what form, eventually winds up as heat. Take heat energy out of water, it gets cooler, and eventually freezes. Add heat energy to ice, it first changes state to liquid, and then starts to get warmer. Keep adding heat energy to it, it keeps getting warmer and warmer. Keep additing heat energy to it, and eventually it changes state to gas ... called "steam". Take heat energy out of the steam, it first changes state to liquid, then gets cooler. etc. etc.
As much or as little as you want. Watt is a unit of power, not of energy. If you use less watts, it will take longer to heat the water, but it will still work.
Three main factors are necessary for evaporation to occur: heat energy, a source of water, and an open space for the water molecules to escape into the air. Heat energy provides the necessary kinetic energy for water molecules to break free from the liquid. Without these factors, evaporation cannot take place.
