Breathing as photosynthesis releases oxygen
food as photosynthesis helps the plant to grow
Answer:
Yes, Is a glass window good reflector of heat.
Heat of vaporization of water will be required as water is already at it's boiling point thus heat required will be 540*10=5400 cal
Answer:
their density is only lighter than water because of the air inside. without the air you would sink even if you were holding it firmly.
Explanation:
Answer: 13 grams
Explanation:
The quantity of heat energy (Q) released from a heated substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)
Thus, Q = MCΦ
Since,
Q = 202.8 Joules
Mass of silver = ?
C = 0.240 J/g °C.
Φ = 65°C
Then, Q = MCΦ
202.8J = M x 0.240 J/g °C x 65°C
202.8J = M x 15.6 J/g
M = (202.8J / 15.6 J/g)
M = 13 g
Thus, the mass of silver is 13 grams
