<u>Answer:</u> The amount of energy required to raise the given amount of temperature is 6400 J
<u>Explanation:</u>
To calculate the heat absorbed by the lead, we use the equation:
where,
q = heat absorbed
m = mass of lead = 200 g
c = heat capacity of lead = 0.128 J/g°C
= change in temperature = 250°C
Putting values in above equation, we get:
Hence, the amount of energy required to raise the given amount of temperature is 6400 J
Answer:
1 Oxygen atom has a mass of 16 grams, thus diatomic oxygen weights twice as much- 32 grams. Hence 32 grams is needed.
According to the law of conservation of mass, the mass of reactants will be equal to the mass of the products. The mass of products and reactants will only differ during a nuckear reaction
Changing of the physical state of water is not a nuclear reaction. So becoz of that the mass will remain constant without any change.
