Answer: Hotspot: A hotspot is a physical location where people can access the Internet, typically using Wi-Fi, via a wireless local area network (WLAN) with a router connected to an Internet service provider. ... While many public hotspots offer free wireless access on an open network, others require payment.
A hot spot is an area on Earth over a mantle plume or an area under the rocky outer layer of Earth, called the crust, where magma is hotter than surrounding magma. The magma plume causes melting and thinning of the rocky crust and widespread volcanic activity.

Work allows energy to be transferred from one object to another. To do work, an agent must exert a force on an object over a long distance.
When work is done, energy is transferred from the agent to the object, resulting in a change in the motion of the object (more specifically, a change in the object's kinetic energy).
What is energy?
Energy is essential to human society and has numerous health benefits. However, each energy source poses some health risks. This article examines the health consequences of each major source of energy, focusing on those with the greatest global impact on disease burden. The harvesting and burning of solid fuels, coal, and biomass have the greatest health consequences, primarily in the form of occupational health risks and household and general ambient air pollution. In the world's poorest households, a lack of access to clean fuels and electricity poses a particularly serious health risk. Although energy efficiency has many advantages, energy use is essential to human society and has numerous health benefits.

Answer:
see below
Explanation:
1. Heat energy is added to the substance, weakening the electrical attraction between molecules.
2. Both the melting point and boiling point are lower.
3. dipole
4. Water and ethanol have different molecular structures.
5. The lone pairs of electrons in the oxygen atom causes the molecule to be bent; the oxygen atom has a partial negative charge, while the hydrogen atoms have partial positive charges.

Answer:
Here's what I get
Explanation:
i. E = mc²
E = energy
m = mass
c = the speed of light
"Energy equals mass times the square of the speed of light.”
The equation says that energy and mass are interchangeable. If you multiply the mass of an object by c², you get its equivalent and of energy.
The SI base units for energy are kg·m²s⁻².
The most common derived unit is the joule (J). Others are the newton-metre (N·m), kilowatt-hour (kWh), watt-second (W·s), and volt-coulomb (V·C).
ii. Nuclear vs chemical reactions
a. Alpha decay
A nuclear reaction — like α decay — takes place in the nucleus of an atom.
An element becomes a different element.
b. Chemical reaction
Na· + ·Cl ⟶ Na⁺ + Cl⁻
A chemical reaction — like the formation of NaCl — involves rearranging the electrons, which are outside the nucleus.
The elements do not change.
Salt still consists of sodium and chlorine.
