When a system looses heat it is considered exothermic and vice-versa endothermic. But something that is considered cold to us can loose heat and become colder. It is therefore necessary to use a specific temperature when referring to the change.
Answer:
Explained
Explanation:
Your tutor is completely wrong here. Ampere and volt are both completely different concept. Ampere measure current in circuit, whereas volt measure the potential difference across two points in circuit. It is due to this difference in the potential that leads to flow of current in the circuit. The potential difference is the cause and current is the effect.
