Latent heat of vaporization of water is 540 cal/g, and specific heat of water is 1 cal/(g•°C) how much heat (in calories) is required to bring 61 g of water at 41°C to 100°C steam?

Hi please help: A heat transfer of 8.0 x 10^5 J is required to convert a block of ice at -10 degrees Celsius to water at 12 degrees Celsius What was the mass of the block of ice? Express answer using two significant figures in kg

A 60.0-kg runner expends 359 W of power while running a marathon. Assuming 12.5% of the energy is delivered to the muscle tissue and that the excess energy is removed from the body by sweating, determine the volume of bodily fluid (assume it is water) lost per hour. (At 37.0°C the latent heat of vaporization of water is 2.41 ✕ 106 J/kg.) cm3

Calculate the amount of heat needed to change the temperature of 2 kg of steam from 110 0C to -4 0   Use the following in working this question: Specific heat of water = 1 kcal/kg.0c Specific heat of ice = 0.5 kcal/kg.0c Specific heat of steam = 0.5 kcal/kg.0c Latent heat of fusion = 80 kcal/kg Latent heat of vaporization = 540 kcal/kg

Substance Y · Substance X 140 BE The graph depicts the temperature curves for two substances labeled as substance X and Y. Why does the temperature remain constant as heat is added to each substance in the regions labeled A to B, C to D, and A' to B', and C' to D'? Based on the curve for either substance X or substance Y and using what you know about the particulate nature of matter, and the relationship between temperature and potential or kinetic energy, describe why adding heat leads to the step-wise change in temperature depicted in the graphs.
