Previous Question: Insects constitute the largest animal group on earth. About 25-30% of the insect species are known to be herbivores. In spite of such huge herbivore pressure, globally, green plants have persisted. one possible reason for this persistence is – (A) Food preference of insects has tended to change with time (B) Herbivore insects have become inefficient feeders of green plants (C) Herbivore population has been kept in control by predators (D) Decline in reproduction of herbivores with time Next Question: Two bulbs of identical volumes connected by a small capillary are initially filled with an ideal gas at temperature T. Bulb 2 is heated to maintain a temperature 2T while bulb 1 remains at temperature T. Assume throughout that the heat conduction by the capillary is negligible. Then the ratio of final mass of the gas in bulb 2 to the initial mass of the gas in the same bulb is close to - (A) 1/2 (B) 2/3 (C) 1/3 (D) 1

Two rods, one made of copper and the other steel of the same length and cross sectional area are joined
together. (The thermal conductivity of copper is 385 J.s–1 .m–1. K–1 and steel is 50 J.s–1.m–1.K–1.) If the copper
end is held at 100ºC and the steel end is held at 0ºC, what is the junction temperature (assuming no other heat
losses) ?
