Q1: Write a paragraph on blood donation camp?

Q2: Write a paragraph on pressure cooker?

2 Pressure cookers work on the principle that as the pressure increases boiling point of water increases and the steam is produced from water.The pressure cookers are designed in such a way it controls the escape of steam. When the steam is not allowed to escape, it builds up more pressure which allows the water in the cooker to start boiling with increase in temperature.Thus higher the temperature of water makes cooking faster. And the steam covering the entire cooker completely helps to heat and cook food evenly and quickly.

We see from the above that the steam is formed at faster rate because the boiling point is directly proportional to pressure, i.e. if the pressure increases boiling point also increases.

Blood is the life line of human existence. Loss of large quantity of blood may cause death. A healthy human being can donate blood once in eight weeks. Many lives can be saved through voluntary donation of blood in the blood donation camp. The blood collected in such camps can be useful at the times of medical emergency. We regularly read about several accidents, earth quakes and natural calamitiesin the newspapers. If we donate blood today, it may be useful for not only others but, our own family and friends too in future.Donating blood is a noble cause and hence, gives us inner satisfaction.Blood donation should be carried out keeping in mind the safety measures and the health conditions of the donor.we are after all saving a person like us......
