As the steam touches the skin, it undergoes a phase change and releases latent heat due to the phase change. As it reaches equilibrium, it releases sensible heat. We calculate as follows:
Q = latent heat + sensible Heat
Q = 2.26 kJ / g (50.0 g) + 50.0 g ( 4.18 J / g C) (37 C - 100 C) ( 1 kJ / 1000 J)
Q = 99.833 kJ
Answer:
d
Explanation:
because is a reducing agent, O 2 is an oxidizing agent.
Answer:
an electron with element with large number of valence electron and large atomic <u>radius</u>
Explanation:
Given that,
Mass of a skier, m = 55 kg
The vertical distance between start and finish is 10 m.
(a) The potential energy of a skier is given by :

(b) When she reaches the bottom of the hill, the potential energy is converted to kinetic energy. So,

Hence, her potential energy is 5390 J and at the bottom of the hill she is moving with a speed of 14 m/s.
