Given the energy obtained by the human body from a candy bar = 915 kJ
Energy required to vaporize 1 g of water at it's boiling point is referred to as heat of vaporization of water.
The heat of vaporization of water = 2260 J/g
Mass of water that can be vaporized by 915 kJ of heat =
Density of water = 1 g/mL
Converting mass to volume in L of 405 g water:
Therefore, 0.405 L of water can be vaporized
False. Because gas to a liquid is called condensation
Answer:
4 joules

Explanation:
I think the best answer from the choices is option B. <span>Atmospheric chemists think that Earth’s first atmosphere contained no oxygen atoms. It was believed that the early atmosphere of the Earth was due to the volcanic activities which are not known to produce oxygen atoms. Therefore, chemists think that there were no atoms of oxygen.</span>
Answer:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. ... Solids, liquids and gases all expand when heat is added.
