General Science Test 2 General Science Please enter your email: 1. Why a metal tea-pot is provided with an ebonite handle ? Because it is a cheaper material. Because it is unbreakable. Because ebonite is very beautiful to look at. Because ebonite is a bad conductor of heat. Therefore it does not get hot easily. 2. Why cooking is quicker in a pressure cooker ? Because the accumulation of steam in the pressure cooker increases pressure inside the cooker. Because the accumulation of steam in the pressure cooker’ increases the temperature inside the cooker. Because of the increase in the penetrating power of the steam. Because the accumulation of steam in the pressure cooker increases both pressure and temperature inside the cooker. 3. Why water pipes are in danger of bursting in extremely cold weather ? Because short-range repulsive forces are produced between water’ jand pipes. Because water freezes and hence expands. Because water pipes contract in extremely cold weather. Because water exerts greater pressure at lower temperatures. 4. Why wet clothes dry more quickly on a warin day than on a cold day ? Because humidity is less on warm days. Because high temperature of air fastens’ evaporation. Because wind blows faster on warm days. ecause clothes expand on warm days. Thus more surface area is exposed. 5. At what temperature water has maximum density ? 2 degreeC. 0 degree C. 1 degreeC. 4 degreeC. 6. Why do people prefer to use white clothes in summer ? Because white clothes absorb no heat. Because white clothes shine more in summer. Because white clothes absorb more heat. Because white clothes absorb less heat. 7. At what degree the readings in both the Centigrade and Fahrenheit scales are exactly the same ? 39 degree. 38 degree. 37 degree. 40 degree. 8. Why does a thermos flask keep cold liquid cold and belt liquid hot Because the walls of the thermos flask are very thick. Because the thermos flask is double-walled and the spacee, inbetween contains air under pressure. Because thermos flask is constructed in such a way that heat can neither leave the flask nor enter the flask. Because of a special inner lining in the thermos flask. 9. Why does a cheap clock lose time in summer ? 1ecause the pendulum gains length in summer. Because days are longer in summer. Because the pendulum loses length in summer. Because the dial of the clock expands in summer. 10. Wny cooking more difficult on the mountains? Because there is snowfall on mountains. Because fuel for cooking is not easily available on the mountains. Because pressure is low at higher altitudes. Low pressutd lowers the boiling point. Therefore cooking takes longer on the mountains. Because it is cold on the mountains. Loading … Question 1 of 10 Previous PostESL EFL Test 571 Next PostWord Analogy Completing Pair 4
