a student built a fire using coal. the coal started to burn. which statement best describes the energy changes that occurred.
A. the chemical energy stored in the coal changed to thermal energy and light energy
B. the thermal energy stored in the coal changed to light energy and chemical energy.
C. the light energy and thermal energy stored in the coal changed to mechanical energy.
D. the light energy and thermal energy stored in the coal changed to chemical energy

Answers

Answer 1

Answer:

98% sure the answer is A, as coal, when burning, releases thermal and light energy through the fire.

Explanation:

Answer 2
ANSWER: B. The thermal energy stored in the coal changed to light energy and chemical energy.
.
EXPLANATION: thermal energy is already within the coal and because of the light from the fire, that's obviously light energy. And in the end, there is a chemical reaction after the coal burns to ash, and that is chemical energy! I hope this helps!☺️ Please give Brainliest!!

The graph represents the percentages of salt water and fresh water on Earth. What is the percentage of salt water?


1. 3 percent
2. 50 percent
3. 97 percent
4. 100 percent

Answers

Answer:

97.

Explanation:

Though the exact number is 96.5, we can round it up since its 5. When rounding by 10, 5 or more rounds up and 4 or less rounds down. So rounding up of 96.5 is 97. 3)

The percentage of salt water is 97 percent on Earth. Hence, option (3) is correct.

What is water distribution on Earth?

Saline seawater makes up the majority of the water in the atmosphere and on the surface of the Earth, with fresh water making up less than 1% of the total. The majority of the water on Earth is saline or salt water, with an average salinity of 35 ‰ (or 3.5%, or around 34 grams of salts in 1 kg of saltwater), though this fluctuates slightly depending on the amount of runoff absorbed from nearby land.

Over 97% of the water on Earth comes from the oceans and marginal seas, saline groundwater, and water from saline closed lakes, however no closed lake holds a large amount of water on a global scale. Except when evaluating water quality in arid places, saline groundwater is rarely taken into account.
