Assertion (A): 0 °C = 273.16 K. For our convenience we take it as 273 K after rounding off the decimal

Reason (R): To convert a temperature on the Celsius scale you have to add 273 to the given temperature

Assertion (A): The skill of estimation is important for all of us in our daily life.

Reason (R): The skill of estimation reduces our consumption of time

Assertion(A): The scientifically correct expression is “ The mass of the bag is 10 kg”

Reason (R): In everyday life, we use the term weight instead of mass

Assertion (A): The distance between two celestial bodies is measured in the unit of light year

Reason (R): The distance travelled by the light in one year is one light year

Read the passage and answer the questions given below.

Mass is the amount of matter contained in an object. Measurement of mass helps us to distinguish between a lighter and a heavier body. Beam balance, spring balance and electronic balance are used to measure mass of different objects. The SI unit of mass is the kilogram (kg). But different units are used to measure the mass of different objects. E.g. weight (mass) of a tablet is measured in milligrams (mg), weight of a student is measured in kilogram (kg) and weight of a truck with goods is measured in metric tons. 1 metric ton is equal to 10 quintals and 1 quintal is equal to 100 kg. 1 gram is equal to 1000 mg.

The value of 1 metric ton is equal to
