We understand that heat or thermal energy can flow from one substance to another, but could it be possible that coldness is an attribute that flows from one object to another? If this were true, how would our understanding of temperature change? Explain why heat must flow from warm to cold.

Which term describes the amount of thermal energy required to melt or freeze 1 kg of a substance? a. specific latent heat of vaporization b. latent heat of vaporization c. latent heat d. specific latent heat of fusion

thank you

Answer #1

heat can be flow from one body to other body when there is temperature difference between two bodies .so it must flow from higher to lower.

NH4NO3, whose heat of solution is 25.7 kJ/mol, is the one substance that can be used in a cold pack. If the goal is to decrease the temperature from 25 to 50 degrees Celsius, how many grams of NH4NO3 should we use for every 100.0g of water in the cold pack? Assume no heat was lost outside of the cold pack, and the specific heat of the resulted solution was the same as water, or 4.184 J/g degrees C. Please...

A substance has a melting point of 20°C and a heat of fusion of 2.6×104 J/kg. The boiling point is 150°C and the heat of vaporization is 5.2×104 J/kg at a pressure of 1.0 atm. The specific heats for the solid, liquid, and gaseous phases are 600 J/(kg·K), 1000 J/(kg·K), and 400 J/(kg·K), respectively. The quantity of heat required to raise the temperature of 3.0 kg of the substance from 3°C to 118°C, at a pressure of 1.0 atm, is...

Specific Heat The heat capacity of an object indicates how much energy that object can absorb for a given increase in that object's temperature. In a system in which two objects of different temperatures come into contact with one another, the warmer object will cool and the cooler object will warm up until the system is at a single equilibrium temperature. Note the difference between the terms molar heat capacity, which has units of J/(mol⋅∘C), and specific heat, which has...
