Concept Introduction:
Endothermic Reactions:
The endothermic process is a term that describes a reaction where the system absorbs the energy from its surrounding in the form of heat. Few examples of endothermic process is photosynthesis, evaporating liquids, melting ice.
Exothermic reaction:
The exothermic reaction is the opposite of an endothermic reaction. It releases energy by light or heat to its surrounding. Few examples are neutralization, burning a substance, reactions of fuels, deposition of dry ice, respiration.

Interpretation:
The heat is absorbed or released when freezing of

- sUse information from Figure 15.24 to calculate howmuch heat is required to vaporize 4.33 mol of waterat 100°C.arrow_forwardRefer to Figure 11.12 to answer these questions: (a) You heat some water to 60 C in a lightweight plastic bottle and seal the top very tightly so gas cannot enter or leave the carton. What happens when the water cools? (b) If you put a few drops of liquid diethyl ether on your hand, does it evaporate completely or remain a liquid? Figure 11.12 Vapor pressure curves for diethyl ether [(C2H3)2O], ethanol (C2H5OH), and water. Each curve represents conditions of T and P of which the two phases, liquid and vapor, are in equilibrium. These compounds exist as liquids for temperatures and pressures to the left of the curve and as gases under conditions to the right of the curve. (See Appendix G for vapor pressures for water of various temperatures.)arrow_forwardThe amount of heat required to melt 2 lbs of ice is twice the amount of heat required to melt 1 lb of ice. Is this observation a macroscopic or microscopic description of chemical behavior? Explain your answer.arrow_forward
- The temperature remains constant as energy is added to a substance. How may the substance be changing? a. from a gas to a solid b. in the amount of kinetic energy c. from a liquid to a gas d. from a liquid to a solidarrow_forwardWhat property of water explains why water inside the tiny cracks in rocks helps the latter break when it freezes? a. Water has a high boiling point b. Water has a high surface tension c. Water has a greater volume in its solid state d. Water has a high heat of vaporizationarrow_forwardTemperature at which the vapor pressure of a liquid is equal to the atmospheric pressure above the liquid. a. absolute zero b. boiling point c. Boyle's Law d. Charles' Law e. cohesive force f. condensation g. disruptive force h. kinetic energy i. law of conservation of matter j. melting point k. potential energy l. sublimationarrow_forward
- a. Water is good solvent. Relate this property to issues of pollution. b.Water has a high specific heat. Relate this property to changing climate and the capacity of bodies of water to act as temperature buffer. c. The boiling point of water is unusually high. Relate this property to questions on small water bodies drying up.arrow_forwardwhich of the following substances would have the least amount of heat of formation A. Gaseous ammonia B. Liquid water C. Solid carbon dioxide D. Soilid carbon (or graphite)arrow_forward2. Calculate the amount of heat needed to melt 120.0 g of pure ethanol. Calculate the amount of heat needed to raise the temperature of 2.34 moles of pure liquid ethanol from -84.0 °C to 21.0 °C. (Ethanol melts at-117.3 °C) 3.arrow_forward
