Answers
Answer:
(i)Unit Joule
As a form of energy, heat has the unit joule (J) in the International System of Units (SI). However, in many applied fields in engineering the British thermal unit (BTU) and the calorie are often used. The standard unit for the rate of heat transferred is the watt (W), defined as one joule per second.
(ii)Mole.
Explanation: Amount of substance (also called chemical amount) is a quantity defined by standards to measures the size a group of individual elementary entities, such as atoms, molecules and electrons, along with other particles. ... The SI unit for amount of substance is the mole (mol).
(iii)Aqueous solution of ionic compounds
Ionic compounds dissolve in water by a process called dissociation. Water molecules separate the cations and ions by means of ion-dipole attractions to form hydrated ions. These hydrated ions are electrolytes and conduct an electric current.
(iv) Dehydration is a deficiency of water in the body. Vomiting, diarrhea, excessive sweating, burns, kidney failure, and use of diuretics may cause dehydration. People feel thirsty, and as dehydration worsens, they may sweat less and excrete less urine.
(v)Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent.
