Q1
Which of the following statements is incorrect?
[A]. Dividing materials into groups make it convenient to study their properties
[B]. Materials are grouped together on the basis of only similarities
[C]. Different types of materials have different properties
[D]. Objects around us made up of a variety of materials
Answer: Option B
Explanation:Materials are grouped together on the basis of similarities and differences in their properties. In everyday life, we often group materials for our convenience.
Q2
The space between particles is maximum in
[A]. Solids
[B]. Liquids
[C]. Gases
[D]. Both solids and liquids
Answer: Option C
Explanation:In solids, particles are tightly packed. In liquids the space of particles is larger than solids but smaller than gases. The space between particles is maximum in gases. Generally, they are loosely packed.
Q3
Wood is used as a fuel. Which property makes it suitable for this purpose
[A]. Combustibility
[B]. Density
[C]. Viscosity
[D]. Immiscibility
Answer: Option A
Explanation:The term “combustibility” refers to the tendency of a substance to burn as a result of fire or chemical reaction. It is can be expressed as a property that is a measure of how easily a substance will ignite or burn.
Q4
Which of the following will float on water?
[A]. Mud piece
[B]. Cotton
[C]. Wood piece
[D]. Metal
Answer: Option C
Explanation:Cotton ball initially floats on water but after few minutes it sinks because it absorbs water. All the materials, which are lighter than water, float on water. Wood piece does not sink in any circumstances. Here option [C] will be your answer. So, don’t be confused.
Q5
Strongest intermolecular force of attraction founds in
[A]. Gaseous
[B]. Solids
[C]. Liquids
[D]. Plasma
Answer: Option B
Explanation:In solids, particles are tightly packed. In liquids the space of particles is larger than solids but smaller than gases. The space between particles is maximum in gases. Generally, they are loosely packed. Hence, intermolecular force attraction found strongest in solids, weaker in liquids and weakest in gases.
Q6
There are given some name of the objects. Pick out the odd ones
[A]. Apple
[B]. Orange
[C]. Tomato
[D]. Basketball
Answer: Option D
Explanation:All are rounded eatable objects, except basket-ball. Hence, option [D] will be your answer.
Q7
Boojho asked a question to Paheli that which of the following is a good conductor of heat? Would you help her?
[A]. Wood
[B]. Glass
[C]. Graphite
[D]. Rubber
Answer: Option C
Explanation:Among of these, here graphite (non-metal) is a good conductor of heat.
Q8
Paheli asked a question to Boojho, that name the property of substances which allows the heat to pass through it?
[A]. Lustre
[B]. Conductor
[C]. Opaque
[D]. Insulator
Answer: Option B
Explanation:The materials which allow heat to pass through them easily are “conductors” of heat. For examples, aluminum, iron and copper.
The materials which do not allow heat to pass through them easily are poor conductors of heat such as plastic and wood. Poor conductors are known as “insulators”.
Q9
In generally, we have seen iron rods present in windows. Because of which properties of metal, we use it?
[A]. Opaque
[B]. Lustre
[C]. Good conductor of heat and electricity
[D]. Hard and Strong
Answer: Option D
Explanation:We know that some materials are hard, lustrous, malleable, ductile, sonorous and good conductors of heat and electricity, called metal. Iron is very hard and strong metal and it is found everywhere and relatively cheaper than any other metals. Therefore, we use an iron metal or rod in window as well as door lock.
Q10
Which of the following is correct about pure water?
[A]. It is good conductor of electricity
[B]. It is a bad conductor of electricity
[C]. It is a semi-conductor of electricity
[D]. It behaves like superconductor
Answer: Option B
Explanation:Water is a conductor of electricity. Pure water is actually a good insulator. Tap water can be a good conductor due to calcium, magnesium, and carbonate ions, or other substances. Any impurities, like salts, in the water enable it to conduct electricity. Pure water does not conduct electricity. This is because pure water do not contain any salts or components.
