In conducting three trials measure the distance that a car would roll down an inclined ramp at a given height, which of the following sets of data exhibit precision? Explain why. a. 25m, 26m, 32m b. 24m, 25m, 24.5m c. 21m, 21m, 25m
What is (b) because the data collected in each trial is close to each other

Describe the flow of heat energy as an ice cube changes phases (melts) into liquid water
What is - the ice molecules absorb (gains) heat energy, causing its particles to move faster as it melts to become a liquid?

Use Ohm's Law to find the resistance of a circuit whose voltage is 110 and use current is 11 amps. R = V/I (current). Be sure to include units of measure in your answer.
What is - 10 Ohms? R = V/I R = 110/11 = 10

This type of Earth's crust has the greater density causing it to subduct or sink at convergent boundaries ( HINT: It is made up of basalt rock)
What is the oceanic crust?

(a) This process in the water cycle changes liquid water to a gas, water vapor. (b) This process in the water cycle releases of water vapor from plants into the atmosphere
(a) What is evaporation? (b) What is transpiration?
300
A rock is floating in a beaker of water. A conclusion that you can make about density is _________.
What is that the rock is less dense than the water because it is floating? OR the rock has a density less than one g/cm cubed (the density of water)? Less dense objects float and more dense objects sink.

You put a spoon in a cup of hot chocolate and soon the spoon begins to feel warm. This is an example of heat transfer by ___________________.
What is conduction? (heat transfer by direct contact)

A light cord plugged into an outlet to light up a lamp goes through the following energy transformations.
What is - from electrical to radiant (light) to thermal (heat)?

The heating curve of water has 2 flat lines on it. The temperature does not increase during these times even though heat is being added. The heat energy, instead, is going ____________________ _____/ vaporization __/ melting /
What is - going into the water molecules to add movement to change phases? (for melting or for vaporization)
400
If a rock sample has a mass of 12.9 grams and a volume of 3 cm cubed. Then the rock's density would be ______? Hint: D = M/V
What is 4.3 g/cm cubed? (Be sure to include the units of measure!)
400
Land heats up faster than water during the day, so warm air rises over the land and the cool air sinks and is pushed towards the land causing a sea breeze during the day. This is an example of heat transfer by ______________.
What is convection? (heat transfer through liquids/gases by temperature/density differences)
400
A. In a series circuit with 3 lights, if one light burns out then __________________. B. In a parallel circuit with 3 lights, if one light burns out, then _________________.
A. What is - All of the lights in the series circuit will not light because the circuit has been broken and there is only one loop for all three lights? B. What is - The other two lights will be able to light up because each light has its own loop to the power source?

The effects at convergent plate boundaries can be
What is subduction zones that can create volcanic islands/mountains, deep sea trenches, tsunamis and earthquakes (South America) AND collisions that builds mountains and creates earthquakes (Himalaya Mts)

This is the only process in the carbon cycle that removes CO2 from the atmosphere. Plants use this process to make their own food.
What is photosynthesis?

The following substance were poured into a beaker: water (density = 1), oil (density = .75) and mercury (density = 13). Which substance would be at the bottom of the beaker and which substance would be at the top? Be sure to include why!
What is - Mercury would be at the bottom of the beaker because it is most dense. Oil would be at the top because it is least dense and water would be in the middle because its density is in between the two substances.

Describe 2 impacts that the burning down the rain forests would have on the carbon cycle
What is - (1) there would be more CO2 in the air because there would be fewer trees to remove it through photosynthesis? (2) burning the wood (combustion) also adds CO2 to the air that could make the atmosphere warmer?
