Matter(5th Grade > Science ) Questions and Answers
Explanation:-
Answer: Option A. -> 1- Liquid 2- Solid 3- Solid:
A
Water has the fluidic property and it takes the shape of the container it is kept in, a property shown by liquids.
Each sand grain is a solid particle which is a piece from broken rocks. Each sand grain has a fixed shape and volume. It is a solid.
When we squeeze a sponge, it changes shape but returns to its normal shape when we let go of the force. It has a definite shape.
Explanation:-
Answer: Option C. -> Dry ice changes from solid → gas:
C
Dry ice is a solid block of carbon dioxide. When we pour water on dry ice, the temperature goes up and solid ice directly turns into carbon dioxide in the form of gas. The process in which a solid substance directly turns into gas without turning into a liquid is called sublimation.
Explanation:-
Answer: Option C. -> Melting:
C
Melting is a physical process through which a solid is converted into a liquid. When a solid is heated, the distance betweenthe particles increases, forces of attraction decreases. Eventually, the solid converts to liquid.
Explanation:-
Answer: Option B. -> Evaporation:
B
Evporation is the physical process through which a liquid converts to a gas on absorbing heat. For example, liquid water from oceans, lakes, rivers and other water bodies, undergoes evaporation (changes into gas)by absorbing heat from the Sun.
