2. When a frying pan containing cooking oil is kept for long on a burning stove then cooking oil catches fire because-

Its temperature is lower than its ignition temperature.

Its temperature is reached to its ignition temperature.

Its temperature is lower than critical temperature.

Its temperature is higher than critical temperature.

When a frying pan containing cooking oil is kept for a long time on a burning stove, the temperature of the oil gradually increases. As the temperature rises, it eventually reaches the ignition temperature of the oil. At this point, the oil can catch fire spontaneously, without the need for an external ignition source. Therefore, the correct answer is that the temperature of the oil is reached to its ignition temperature.

3

2

1

0

The given sequence follows a pattern of dividing each number by 2 and subtracting 2 from the result to get the next number. Starting with 190, we divide by 2 and subtract 2 to get 94, and so on. Therefore, the missing number in the sequence is obtained by dividing 4 by 2 and subtracting 2, which gives us 1.

5. The basic difference between a living and non living is -

Presence of cytoplasm

Presence of protoplasm

Presence of mitochondria

None of these

The presence of protoplasm is the basic difference between a living and non-living entity. Protoplasm is the living substance within a cell that contains various organelles and is responsible for carrying out the cell's functions. Non-living entities do not have protoplasm as they lack the ability to carry out essential life processes. Therefore, the presence of protoplasm distinguishes living organisms from non-living objects.

6. In a mixture of 120 litres, the ratio of milk and water is 2 : 1. If the ratio of milk and water is 1 : 2 , then the amount of water (in litres) is required to be added is :

20

40

80

120

The initial ratio of milk to water is 2:1, which means there are 80 liters of milk and 40 liters of water in the mixture. If the ratio is changed to 1:2, it means there should be 40 liters of milk and 80 liters of water in the mixture. Since there is already 80 liters of milk in the mixture, we need to add 40 liters of water to achieve the desired ratio. Therefore, the amount of water required to be added is 40 liters.
