How much heat is lost when 2012 grams of stream at 400 K is changed into ice at 263 K?
To determine the heat lost, we need to calculate the heat required to cool the steam from 400 K to 273 K (its condensation point), then the heat required to change it from steam to liquid water, and finally the heat required to freeze the water into ice at 273 K. These steps involve the specific heat capacities of water and steam, latent heat of vaporization, and latent heat of fusion.

Why does the Gulf Stream heat Great Britain?
The Gulf Stream is a current of warm water that has enough warmth left after crossing the Atlantic Ocean to make the climate of the UK mild and wet. If the current ever changed course, and missed the UK entirely, the climate of the UK would change.
How many grams of ice can be melted with 145 grams of 45 degree C H2O?
To calculate how many grams of ice can be melted by 145 grams of water at 45°C, you first need to determine how much heat is required to cool the water to 0°C and then how much heat is needed to melt the ice at 0°C. Use the specific heat capacity of water (4.18 J/g°C) and the heat of fusion of ice (334 J/g) in your calculations. The final result will be the mass of ice melted.
Which rock is formed when they are changed by heat and pressure?
metamorphic rock
When you apply the same amount of heat 5 grams of water and 5 grams of the water the temperature of the limit increases more than the water what can you conclude?
If you apply the same amount of heat to 5 grams of water and 5 grams of another substance, and the temperature of the other substance increases more than that of the water, you can conclude that the other substance has a lower specific heat capacity than water. Specific heat capacity is the amount of heat required to raise the temperature of a substance, so a lower value means that it requires less energy to achieve the same temperature increase.
How much heat energy is produced when 22 grams of propane is burned in a stove?
To determine the heat energy produced when burning propane, we need to know its heat of combustion, which is approximately 50 MJ/kg. For 22 grams (0.022 kg) of propane, the energy released can be calculated as follows: 0.022 kg × 50,000 kJ/kg = 1,100 kJ. Therefore, burning 22 grams of propane produces about 1,100 kJ of heat energy.
The specific heat of gold is 0.031 caloriesgram and degC. If 10.0 grams of gold were heated and the temperature of the sample changed by 20.0 and degC how many calories of heat energy were absorbed by?
The needed heat is:Q = 10 x 20 x 0,031 = 6,2 calories
Why does the Gulf Stream heat Great Britain?
The Gulf Stream is a current of warm water that has enough warmth left after crossing the Atlantic Ocean to make the climate of the UK mild and wet. If the current ever changed course, and missed the UK entirely, the climate of the UK would change.
How much heat energy is absorbed in 65 gram sample whose temperature changed from 45 to 80 degrees celsius?
That completely depends on the specific heat capacity of the substance of which the sample is composed, which you haven't identified. It will take a lot more heat energy to raise the temperature of 65 grams of water 35 degrees than it would take to do the same to 65 grams of iron or yogurt, e.g.
Which rock means 'changed'?
Metamorphic, changed by pressure and heat

When 30 grams of water is converted into steam how much heat is absorbed?
q = mHvq = heatm = mass (30g)Hv = heat of vaporization (2,260J/g)q = (30g)(2,260J/g)q = 67,800JWhen 30 grams of water is converted into steam, how much heat is absorbed?67,800J of heat, also represented as 67.8kJ of heat is absorbed.

it gose to the sun lol
How is heat moved around the Atlantic Ocean?
By warm currents, such as the Gulf Stream.
How many joules of heat are needed to completely vaporize 24.40 grams of water at its boiling point?
The heat of vaporization of water is 40.79 kJ/mol. First, determine the number of moles in 24.40 grams of water. Then, convert moles to joules using the molar heat of vaporization. This will give you the amount of heat needed to vaporize 24.40 grams of water.
