Answer:
D. They have the same number of protons as electrons.
Explanation:
Protons are found in the nucleus of the atom and have a positive charge while electrons orbit around the nucleus and have a negative charge. Usually, in a neutral atom of an element, the number of protons is equal to the number of electrons. This is why the atom has no charge because the positive and negative charges cancel out. When an atom loses an electron its charge turns positive while when it gains an electron its charge turns negative.
Answer:
An alloy is the combination of metals homogeneously.
Explanation:
Alloys can also include other elements in combination with metals e.g carbon and Iron forms steel.
Alloys find a host of application in various industries and domestic use.
Alloying of metals helps to improve the physical and chemical properties of such materials better.
Some materials are alloyed to improve their strength.
Alloying can help heat and electrical conduction of a substance.
Alloys can greatly prevent rusting and produce corrosion resistant metals.
Alloys can provide a better means for a material to be worked.
Alloys can be more durable than original materials.

The pressure would increase. When the temperature change form cold to hot, the gas will find ways to escape from containment. Thus, if it cannot escape that pressure will keep on increasing as the temperature rises.
Answer:
Surface tension
Explanation:
A water strider (water bug) is able to walk on water because of water’s Surface tension.
Surface tension is phenomenon in which in liquid where it shrinks itself to its minimum surface area possible, it is very much visible in water surface because of high attraction between the water molecule.
