Oxygen is a by-product of photosynthesis thus it is not needed for photosynthesis to occur.
Light is needed to provide the energy needed as photosynthesis is endothermic and is also needed to ionise the water molecule to get hydroxide and hydrogen ions and carbon dioxide is what is reduced to starch.
Answer:
Q = 19255.6 j
Explanation:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
Given data:
Mass of water = 46 g
change in temperature = ΔT = 100-0.0 = 100 °C
Heat absorbed by water = ?
Solution:
Specific heat capacity of water = 4.186 j/g. °C
Q = m.c. ΔT
Q = 46 g×4.186 j/g. °C×100 °C
Q = 19255.6 j
