Hello there!

Question: Which process releases heat?

Explanation: The process the releases heat is called the exothermic process while the process is which heat is absorbed or taken is is called the endothermic process. The answer choices are examples of either endothermic or exothermic processes.

Answer Choices:

A. Grilling Vegetables

B. Frying an egg

C. Boiling water

D. Setting off a firecracker

Correct

D. Setting off a firecracker

Reasons:

A would not be correct since grilling vegetables is an endothermic process in which heat is being taken in to grill the vegetables.

B would not be correct since frying an egg is again taking in heat to fry the egg which is again, an endothermic process.

C would not be correct since boiling water is taking in heat to heat up the water which makes it endothermic process once again.

D would be correct since it is releasing heat when the explosion is triggered and you can feel the wave of heat afterwards.

P.S: These are all chemical reactions except for boiling water since that is a physical change.

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
