The specific heat capacity of water is 4.18 J/g°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 change in temperature, we can calculate the heat energy as follows: Q = 15g * 4.18 J/g°C * 25°C = 1567.5 J. Therefore, 1567.5 Joules of heat energy will be required to raise the temperature of 15 grams of water by 25 degrees Celsius.
At -20 degrees Celsius, the saturation vapor pressure of water is about 2.2 millibars. Therefore, to saturate a kilogram of air at this temperature, you would need about 2.2 grams of water vapor.
The specific heat capacity of water is 4.184 J/g°C. The change in temperature is 35.5°C - 21°C = 14.5°C.

At -20 degrees Celsius, the saturation vapor pressure of water is about 2.2 millibars. Therefore, to saturate a kilogram of air at this temperature, you would need about 2.2 grams of water vapor.
The specific heat capacity of iron is 0.45 J/g°C. To calculate the energy required, you can use the formula: Energy = mass x specific heat capacity x change in temperature. Plugging in the values, Energy = 5g x 0.45 J/g°C x (30°C - (-10°C)). This calculation would give you the energy in joules required to raise the temperature of 5 grams of iron from -10ºC to 30ºC.
Specific heat af aluminum is 0.89 J/gC, so I will convert to grams for my convince.3 kg Al (1000 g/1 kg) = 3000 grams Alq = mass * specific heat * change in temperatureq = (3000 grams)(0.89 J/gC)(23 C - 18 C)= 1 X 104 Joules==============( as per significant figures )

You mean how much heat energy will be lost/transferred as you are losing Joules here. All in steam, so a simple q problem and no change of state. 2.67 kg = 2670 grams q = (2670 grams steam)(2.0 J/gC)(105 C - 282 C) = - 9.45 X 105 Joules ----------------------------------- This much heat energy must be lost to lower the temperature of the steam.
The final temperature would be approximately 54.2 degrees Celsius. This can be calculated using the principle of conservation of energy, where the heat lost by the hot water is equal to the heat gained by the cold water.
The specific heat capacity of copper is 0.385 J/g°C. To calculate the heat energy required, you use the formula: Q = mcΔT, where Q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. Plugging the values in, you get Q = 6g * 0.385 J/g°C * (150°C - 100°C) = 92.4 Joules.
The specific heat capacity of aluminum is 0.897 J/g°C. First we need to convert the mass to grams: 3 kg = 3000 g. Then we can use the formula: energy = mass x specific heat x change in temperature. Plugging in the values: energy = 3000 g x 0.897 J/g°C x (23°C - 18°C) = 13,485 J. So, 13,485 Joules of energy is required.
The energy required to raise the temperature of a substance can be calculated using the specific heat capacity formula: Q = mcΔT, where Q is the energy transferred, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature. For aluminum, the specific heat capacity is 0.897 J/g°C. Converting the mass to grams (3000 g), the energy required would be: Q = 3000 g * 0.897 J/g°C * 5°C = 13,455 J.
The specific heat capacity of water is 4.184 J/g°C. The change in temperature is 35.5°C - 21°C = 14.5°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 change in temperature, you can calculate that the heat required is approximately 1554.7 joules.
