Answer:
Work
Explanation:
Work is defined as the ability to use energy in one second and its SI unit is same as energy that is joule.
Work refers to the energy utilized to displace an object over a distance by an external force in one direction and in given time period which can be one second as well.
Hence, the correct answer is "work".
The action or power of focusing one's attention or mental effort.
a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction.
a substance that slows down or prevents a particular chemical reaction or other process, or that reduces the activity of a particular reactant, catalyst, or enzyme.
Answer:
2-octene
Explanation:
the 8-carbon chain (oct); has a double bond (ene) is on the 2nd carbon (2-)
Answer:
Endothermic.
Explanation:
Hello there!
In this case, it is necessary to keep in mind that exothermic processes are characterized by the release of energy and the endothermic processes by the absorption of heat. In such a way, every process from solid to liquid or gas is endothermic as they require energy to separate the molecules and therefore turn out in the phase change. On the other hand, every process from gas to liquid or solid is exothermic as heat is released to rejoin the molecules and produce the phase change.
Therefore, since solid water molecules tend to be well-arranged, it is necessary to add heat to the system to produce the phase change until gas; in such a way, this process is endothermic as energy must be absorbed by the ice.
Best regards!
