A change in matter that produces on or more new substances
Atoms can be the source of both nuclear and chemical energy. Nuclear energy involves the atom's nucleus; chemical energy involves the atom's electrons—subatomic particles that surround the nucleus.
Don't take my word for it but I think it is
1: proteins
2: energy from the sun, carbon dioxide, and water
3: this one is confusing me but I think it would be nutrients from food and oxygen
4: water
Again these are attempts I can't prove these
Answer:
1. Litres
2. minutes
3. Kelvin (K)
4. Kilometer/hour
5. hours
6. Litre
7. metre
8. metre
9. Litres
10. milliliters
Explanation:
1. Coca-Cola is a liquid substance, hence, its volume must be measured in LITRES.
2. This question is related to time I.e. being early, hence, the unit of measurement is MINUTES.
3. The unit of temperature is Kelvin (K). Therefore, water boils at 373K
4. This question is related to speed, whose unit of measurement is kilometer/hour (km/hr).
5. A movie runs with time, which is measured in HOURS.
6. Mineral water is a liquid, which can only be bought per volume. Hence, the appropriate unit is LITRE.
7. Height is measured in metres (m). Therefore, one can say that " the height of your younger brother is 10metres"
8. The length of a substance is also measured in metres.
9. Volume is measured in LITRES
10. Cough syrup is a drug whose volume is quantified by millilitres i.e. a thousandth litre
