<h2>Answer:</h2>
<u>The correct answer is Thermal Energy</u>
<h2>Explanation:</h2>
Thermal energy is the energy that comes from heat. This heat is generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated. Since the matchstick produces heat energy and heat is referred o thermal energy so it is the correct answer.
Answer: The boiling point of a sample of Propanone at 180 kPa is 75 C. The correct answer is 2.
Explanation:
Propanone is more commonly known under the name "acetone." The boiling point of this compound at 180 kPa will be 75 C. It is an organic compound and its formula is (CH3)2CO.
This compound does not any color, it is highly flammable, and volatile. This compound does have a distinguished odor. It is used in labs, in industry settings, and in the home for various things. The human body does produce this compound naturally and the body disposes of this compound.
Answer:
A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water. The neutralization of a strong acid and strong base has a pH equal to 7. The neutralization of a strong acid and weak base will have a pH of less than 7, and conversely, the resulting pH when a strong base neutralizes a weak acid will be greater than 7.

Explanation:
While the sun is an excellent source of energy, not all forms of life can utilize the sun's energy directly. This lesson describes how plants transform the sun's energy into potential energy stored in sugar, how living organisms utilize energy in sugar to perform work, and how the relationship between photosynthesis and cellular respiration is necessary for life.

- Mass (m) = 1 Kg
- Acceleration due to gravity (g) = 9.8 m/s^2
- We know, weight = mass × acceleration due to gravity.
- Therefore, weight of the object
