Answer: Option (d) is the correct answer.
Explanation:
When heat is removed from water then there will be decrease in the kinetic energy of water particles. This is because on removing the heat, collisions between the particles will decrease as a result the energy will decrease. Thus, particles will stop moving randomly from one place to another.
Therefore, kinetic energy of the water particles decreases.
Two objects of the same size will not have the same mass.
<u>Explanation:</u>
Mass is the amount of the matter present in an object.
If the size and shape differs then the mass in that object will also differ.
For example, if we take 2 balls of the same size namely one plastic ball and other one rubber ball.
Both the balls are of same size, but the mass present in plastic ball is lesser when compared to the rubber ball.
So rubber ball has more mass than the plastic ball, and so it is concluded that two objects of the same size will not always have the same mass.
Answer:
Organic fertilizers are those fertilizers that are not artificially produced but are natural and has carbon in them.
Fertilizers in the broad term are used to provide nutrient to the soil and boost growth of crops.
Some of the advantages of organic fertilizers to inorganic fertilizers are:
They do not make crusts on the soil, unlike inorganic fertilizers.
They help add structure to the soil because of the good water movement into the soil
They are easier on the soil because they feed good microbes.
You can classify a metal: when a subject can surely conduct electricity.
examples: if a problem says the unknown object is malleable, or says "on the left side of the periodic table", is a conductor, is shiny, etc.
Metalloids: when a subject is alongside the staircase, uses word "semi-conductor", it depends on if it's malleable or ductile, and depends on whether it's shiny or not, etc.
Nonmetal: is located on the right side of the periodic table, can ONLY be an insulator, is not malleable, is not shiny, etc.
Kinetic energy, so B molecular movement
