Answer:
D
Explanation:
Respiration is the process by which you get energy from food. So energy in food is converted to a form that can be used by the body
Answer:
46.9mg of oxygen
Explanation:
From Henry's law,
Concentration of oxygen (C) = Henry's constant (K) × partial pressure of oxygen in air (p)
K = 1.3×10^-3M/atm O2, p = mole fraction of oxygen in air × pressure of air = 0.21×1.08atm = 0.2268atm
C = K×p = 1.3×10^-3 × 0.2268 = 0.00029484M of O2
Concentration (C) = number of moles of oxygen (n)/volume of water (V)
Volume of water (V) = 4.97L
n = CV = 0.00029484 × 4.97 = 0.001465mole
number of moles (n) = mass of O2/MW of O2
mass of O2 = number of moles of O2 × MW of O2 = 0.001465mole × 32g/mole = 0.0469g = 0.0469×1000mg = 46.9mg (to three significant figures)
Answer:
Radiation and conduction and forced convection
Explanation:
During cooking noodles , i) hot air flows by forced convection.
ii) Heat is distributed from heating source by radiation.
iii) Conduction takes place from container to noodles or product to be cooked.
