Assuming you mean "Does zinc phosphate give off heat during mixing?" Then yes, it does. Only when mixing, will it create heat (that is; when the cement powder is incorporated into the liquid) When mixing zinc phosphate, you generally use a cooled glass slab, to slow down setting time aswell.

No and yes. If the two liquids do not react chemically then its a physical change, called the enthalpy of mixing, heat of mixing, which can be exothermic or endothermic. If the two liquids react then the heat produced would be chemical.
A firework explosion gives off heat.
the day is warmer than it is at night is because, during the day the sun gives out heat waves (this is called radiation) to the earth. But at night the sun radiation is shining at the oppsite of the earth.
No, endothermic reactions absorb heat. Exothermic gives off heat.
Exothermic Reaction.
Heat rash does not need antibiotics.
Heat in the atmosphere is distributed in vertical mixing process by means of convection. It is also known as the process of vertical distribution.

No, no heat is involved when mixing baking powder and water.
Convective mixing is the entrainment and deepening of the mixed layer in a lake due to heat loss generally in combination with wind forcing. Convective mixing is the entrainment and deepening of the mixed layer in a lake due to heat loss generally in combination with wind forcing.
Capsaicin is the compound in a chili that gives the heat.
No and yes. If the two liquids do not react chemically then its a physical change, called the enthalpy of mixing, heat of mixing, which can be exothermic or endothermic. If the two liquids react then the heat produced would be chemical.
Any object which is cooler than its surroundings absorbs heat and any that is warmer, gives off heat.
Storage can be a variety of materials, stones and water are two. Solar heat during the day heats up storage source and gives off heat during nighttime hours. I live in Minnesota and use wood heat during the day and receive heat off of objects and structure itself during nighttime hours. A well insulated structure is very important to this or any heat/cooling source.
exothermic reactions-gives off heat
Exothermic gives off energy, commonly as heat. Endothermic absorbs heat.
