The mass of magnesium should be less than 0.09g to enable a faster reaction rate. Magnesium reacts to form a white coating around it which stops the reaction. The lesser the gram the faster the reaction before the coating is formed. It is also advisable to use magnesium fillings to increase the rate of reaction.
Answer: Option (c) is the correct answer.
Explanation:
Temperature is used as for measuring the average kinetic energy present in a substance or object.
The internal kinetic energy obtained by the molecules of an object is known as thermal energy.
Hence, temperature measures the thermal energy of an object.
Whereas when this thermal energy flows from a hotter object to a cooler object which are placed adjacent to each other then it is known that heat is flowing.
Thus, we can conclude that heat differ from temperature as temperature measures thermal energy, and heat is the flow of thermal energy.
