Which important change in electronic devices, such as televisions and computers, is a result of the use of metalloids as semiconductors?
a) electronic devices have become smaller.
b) electronic devices are now more brittle.
c) electronic devices now use more energy.
d) electronic devices have become more expensive.

Option (A) Electronic devices have become smaller.

Explanation:

Semiconductor devices are the devices which are based on the properties of the  semiconductor materials like  germanium, silicon, gallium and arsenide. The commonly used materials in electronic devices are the silicon and  germanium because of their low cut off voltages i.e 0.7 v and 0.3 v. Semiconductor materials made the electronic devices smaller as they replaced the Vacuum tubes which was bulky with high operating voltage, high power consumption.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
