a) how much heat is required to convert the ice to water that is also 0.00 C?

b) how much heat would be required to warm this water from 0.00 C to 17.50 C?

HELP!!

I think the fusion is 333 J/g at 0 C... But I'm not sure what to do with that.

How much heat energy is needed to transform 125 g of ice at O degrees Celsius to warm water at 80 degrees Celsius?

How much heat in kilojoules is required to warm 10.0 of ice, initially at -10.0, to steam at 120. The heat capacity of ice is 2.09 and that of steam is 1.84 .

I want the right answer

To answer these questions, we need to calculate the amount of heat required using the specific heat capacity formula:

Q = m * ΔT * c

Where:
Q is the heat energy in joules (J)
m is the mass in grams (g)
ΔT is the change in temperature in degrees Celsius (°C)
c is the specific heat capacity in J/g°C

a) To convert ice to water at 0.00°C, we need to calculate the heat required for the phase change (also known as the heat of fusion).

The heat of fusion (ΔHfus) represents the amount of heat energy required to convert 1 gram of a substance from the solid phase to the liquid phase at its melting point.

Given that the heat of fusion for water is 333 J/g at 0.00°C, we can use this value in our calculation.

Since we want to convert all the ice to water, the mass (m) will be the mass of the ice.

So the formula becomes:
Q = m * ΔHfus

To get the value of Q, we need to know the mass of the ice. Once we have the mass, we can multiply it by the heat of fusion to get the total heat required.

b) To warm the water from 0.00°C to 17.50°C, we can use the specific heat capacity of water, which is 4.18 J/g°C (rounded to two decimal places).

So the formula becomes:
Q = m * ΔT * c

Here, m is the mass of the water, ΔT is the change in temperature (17.50°C - 0.00°C = 17.50°C), and c is the specific heat capacity of water.

To calculate Q, we need to know the mass of the water.

Once we know the mass, we can substitute it into the formula along with the specific heat capacity and the temperature change to find the total heat required to warm the water.

Remember to check the units in the problem and convert them if necessary to ensure the calculations are done correctly.
