I made up these questions for a test, are they good? Try and answer them?

Question

Describe what is happening during these energy transformations.

1. After lunch, a boy rides his bike to his friends house.

2. A driver fills his car with gas and then drives three hundred miles.

3. The electris toaster is plugged into the outlet and is used to make dinner.

4. Sunlight shines on a tree.

5. Coal is burned in the furnace of a power plant.

OKay, those are the questions i made. im making a test for a student im tutoring in science. ive gotten pretty much all of the answers, but i need to know what you think the answer is.

btw, its on EXPLORING ENERGY --

ENERGY TRANSFORMATIONS.

&& if u have the same answers & as much feedback as u can give, then 10 points to you!

Answer 1

yay i love science favourite subject okay here i go

1. the energy in the food which could be glucose or fructose is converted into chemical energy which is used to ride hes bike to his friends house

2. the chemical energy is converted into mechanical energy because the fuel is heated very quickly in the engine

3. electrical energy which comes from the outlet in the wall is converted into heat energy in the toaster which is used to cook the dinner

4. solar energy which is from the sun is changed by photosynthesis into chemical energy stored in the carbohydrate molecules in plant cells for food

5. the coal is chemical energy which is then burned and converted in electrical energy for the power plant to use

i think i got that right not quite sure I'm good at chemistry and biology (biology is the better one) these are some kinda tuff questions what grade is this for there good questions tho tuff but good

Answer 2

1.) chemical (food/drink)>Physical

2.)Chemical(combustion of fuel)>thermal(combustion)> Physical (movement from piston all the way to the tires)

3.)electrical>Thermal>Chemical(food cooking)

4.)chemical(sun burning)or nuclear>thermal>Chemical(photosynthesis)

5.)chemical>thermal

Answer 3

?????????????????????

hahahahahahahahahahahahahahahahahah

kno u can c how much i pay attention in class lol

srry idk wat ur even sayin lol

Answer 4

umm... yea...  i have noooo clue... so its not my fav lol

Answer 5

all of above

NO

Answer 6

1. chemical energy to kinetic energy

2. chemical to electrical to kinetic and sound

3. electric to heat

4. solar to chemical

5. chemical to electrical..
