Four beakers of four different sizes are filled with water to the same depth. The temperature of the water is the same in all four beakers. If 100 grams of ice are added to each beaker, in which beaker will the temperature change the least? A. The temperature changes will be the same in all four beakers. B. W C. Y D. X

Three beakers labelled as A, B and C each containing 25 mLof water were taken. A small amount of NaOH, anhydrousCuSO4 and NaCl were added to the beakers A, B and Crespectively. It was observed that there was an increase inthe temperature of the solutions contained in beakers A andB, whereas in case of beaker C, the temperature of thesolution falls. Which one of the following statement(s) is(are)correct?(i) In beakers A and B, exothermic process has occurred.(ii) In beakers A and B, endothermic process has occurred.(iii) In beaker C exothermic process has occurred.(iv) In beaker C endothermic process has occurred.(a) (i) only (b) (ii) only(c) (i) and (iv) (d) (ii) and (iii)

A student had a glass of water at 25°C. He put some ice in it. Once the ice melted, he found that the water's temperature had decreased to 18°C.The student puts the same amount of water at 25°C into another glass. He then adds more ice to this glass than he had added to the first glass. Which statement correctly explains what will happen after the ice melts? A. The water will be colder than 18°C because more thermal energy would have been added to it. B. The water will be warmer than 18°C because it would have received more heat from the ice. C. The water will be warmer than 18°C because melting would have taken place for a longer time. D. The water will be colder than 18°C because more heat would have flowed from it to the ice.

You have two containers of water.  One container A holds 100 mL and container B holds 2000 mL of water.  What temperature will each container boil?acontainer A will boil at a lower temperature because it has less waterbboth containers will boil at 100°Cccontainer B will boil at a lower temperature because it has more waterdcontainer B will boil at a higher temperature because it has more water

A chemist mixes 500 g of lead at 500°C with 1,200 g of water at 20°C. She then mixes 500 g of copper at 500°C with 1,200 g of water at 20°C. The specific heat capacity of lead is 0.1276 J/g°C and the specific heat capacity of copper is 0.3845 J/g°C. What will be true about the final temperatures of the two systems?  A. The final temperature of the lead-water system will be equal to the final temperature of the copper-water system.  B. The final temperature of the lead-water system will be higher than the final temperature of the copper-water system.  C. The final temperature of the lead-water system will be lower than the final temperature of the copper-water system.  D. Cannot be determined from the given information.
