How many grams of steam is there if the water was 25g?
To calculate the mass of steam produced from 25g of water, we need to consider the phase change from liquid water to steam. The specific heat capacity of water is 4.18 J/g°C, and the heat of vaporization of water is 2260 J/g. By using the formula Q = mcΔT for the water and Q = mL for the phase change, where Q is the heat energy, m is the mass, c is the specific heat capacity, ΔT is the temperature change, and L is the heat of vaporization, we can determine the mass of steam produced.
