Which of the following can be attributed to water’s high specific heat? A- oil and water do not mix well B-ice floats on water C- sugar dissolves in hot tea faster than in iced tea D- A lake heats up more slowly than the air around it

Precipitation is one of the main processes involved in the water cycle. It involves the formation of water falling to the ground from cloids and transforming into either rain, snow sleet, or hail Which of the following properties of water can be used to explain why when water falls from clouds it is able to form a rain drop? O cohesive ability O universal solvent O expansion upon freezing O moderation of temperature

Can the heat capacity of water be considered small or large? What is the biological significance of that characteristic?

Energy can be classified into both kinetic energy and potential energy. Which image best illustrates kinetic energy? A baseball in a pitcher's hand. A puck slides past a goalie. A book balances on someone's head. A boulder sits on a cliff. None of these. a. b. C. d. e. a d C b

Which of the following is due to water's specific heat? A lake heats up more slowly than the air around it. Ice floats on water. Oil and water do not mix well. Sugar dissolves in hot tea faster than in iced tea.

You measure the thermal energy of a pot of boiling water and water in a swimming pool. The has the highest thermal energy because it has pot of water; a lower volume

You are stranded on a lifeboat with several other people in the middle of the ocean.  You have run out of clean drinking water and are very thirsty.  The others have started to drink the seawater to quench their thirst. Since you’re waiting for rescue (and are a top notch AP Biology student), you decide to solve a couple of water potential problems to determine if drinking sea water is a good idea or not.  a) The majority of dissolved ions in seawater is NaCl, roughly a 0.5M concentration.  The ionization constant of NaCl is 2.0.  Calculate the solute potential for seawater if you know that the water is 2°C. b) Your own cells have a 0.15M concentration.  Calculate the solute potential for your own cells, knowing that body temperature is 37°C. c) Using your knowledge about water potential, if you drink the seawater, wat will happen when the seawater comes into contact with your body’s cells? Note: ΨP for animal cells is zero

The ratio between saturated an unsaturated fats in a sample help determine the state of the sample at room temperature. Group of answer choices True False

When water freezes the bonding of its molecules becomes flexible its density increases it expands its molecules come closer to one another
