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.

thank you

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...

Suppose that there are two very large reservoirs of water, one at a temperature of 87.0 ∘C and one at a temperature of 19.0 ∘C. These reservoirs are brought into thermal contact long enough for 40210 J of heat to flow from the hot water to the cold water. Assume that the reservoirs are large enough so that the temperatures do not change significantly. What is the total change in entropy, Δ?tot, resulting from this heat exchange between the hot...

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), andspecific heat, which has units...
