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
The correct answer is D. melting the solid.
Answer:
The correct answer is <em>b. Negative</em>
Explanation:
An electrolytic cell is based on a reduction- oxidation reaction which is non spontaneous. That means that the standard cell potencial (Eº) is negative. For this reason, an electrical potential must be applied in order to force the reaction. Conversely, a galvanic cell is based on a spontaneous redox reaction, so the galvanic cell produces electrical energy.
Answer:
yeh they are all correct .
Answer:
Data is a specific measurement of a variable – it is the value you record in your data sheet.
