Compared to many other liquids, water has a high heat of vaporization, which means a relatively large amount of heat must be added to the water before the water molecules are moving fast enough to escape the surface as a gas. Which of the following explains why water has a high heat of vaporization?
A Adding heat to the water causes the molecules to move around, and the motion keeps pushing them back below the waters surface
B As water molecules heat up they tend to form more hydrogen bonds with each other, making it difficult for any of the molecules to vaporize.
C Water molecules have a relatively high molecular weight compared to other molecules, so more energy is needed for the water molecules to vaporize.
D Enough heat must be added to water molecules' hydrogen bonds to break the bonds and provide the molecules enough energy to escape the surface..
Answer:
D
Explanation:
Water has a fairly high specific heat, which means that enough heat must be added to it to break the hydrogen bonds between the molecules, allowing them to move freely from each other and escape the water's surface.
Compare a sled’s potential energy at 10 m to its potential energy at 20 m. How does doubling height affect potential energy?
Answer:
It has an exponential effect. In contrast, you can reach a point when an object is so heavy that when dropped, it achieves terminal velocity. Without the factors of drag and general friction, all objects will fall at a velocity of around 9.8 meters per second. They must, however, accelerate to that speed. Increasing the high gives the sled more time to reach its top speed. That is, its potential energy grows.
Explanation:
Fossil fuels such as gas, oil, and coal have what kind of energy?.
Answer:
chemical energy
Explanation:
The energy conversion goes from chemical energy stored in the fuels, to heat energy as it burns which is converted to kinetic energy as it drives large turbines and finally this is converted to electrical energy. The problem with burning fossil fuels is their effect on the environment.
According to the principle of original horizontality, what most likely happened to the rock layers in the background?
Answer:
They were deposited horizontally and then shifted by a geologic event.
Explanation:
Organisms such as jellyfish and sea turtles depend on which ocean movements to find food and avoid predators? *
a. tides
b. waves
c. gravity
d. currents
Answer: D. Currents
Explanation:
A current is the movement of streams under the water. It carries organisms and other matter through the ocean. Jellyfish, although they can swim, mostly rely on currents to float through the water.
Elizabeth wants to test DNA using Restriction Fragment Length Polymorphism (RFLP). What type of DNA sample would MOST likely be successful using RFLP
The type of DNA sample that would MOST likely be successful using RFLP is a sock soaked in human sweat.
What is RFLP?Restriction Fragment Length Polymorphism (RFLP) is a type of molecular marker used to identify samples of DNA.
RFLPs are fragments of different lengths that can be separated by electrophoresis and then identified.

The water in vegetables evaporates over time causing the vegetables to wilt. Why do grocery stores spray water on their vegetables?.
Answer: For aesthetic reasons and to charge extra.
Explanation: Shoppers are more drawn to vegetables with water because they look more hydrated and “fresher”. Vegetables absorb moisture, so they will weigh more, therefore shops can charge more.
