Final P1 Graphing 2023

The graph shows energy production in the United States in 1967 and 2007 for several sources of energy. Which conclusion is supported by the graph?

• In 1967 more energy was produced in oil than in 2007

• More energy was produced in 1967 than in 2007 in every category.

• In 2007, more energy was produced from renewable energy sources than from fossil fuels.

• People in the United States were more concerned about conserving energy in 1967 than they were in 2007.

Which of the following is true about why we want to test only one independent variable at a time?

• Because it is hard to setup a data table with more than one variable

• To better identify what is causing the changes

• It is what has always been done

• It's easier to perform the experiment

What was the net loss in glacier ice thickness between the years 1970 and 1990? type only the number

(a)  

During an experiment, a student measures the mass of ice and of liquid water and then places the mixture into a freezer for a day. The table shows the data.

What will the student have at the end of the experiment?

• 100 grams of ice

• 125 grams of ice

• 125 grams of liquid water

• 150 grams of liquid water

A group of students researched the melting points of some representative elements and made up cards containing the symbol and melting point of each element. They then grouped the cards together to make the portion of the periodic table shown. Which conclusion best fits the group’s data?

• Elements in periods 4,5, and 6  have melting points that increase and then decrease with increasing atomic number.

• Group 2 metals have melting points that decrease with increasing atomic number.

• Elements in a group have melting points that decrease with increasing atomic number.

•   Elements in all groups  metals have melting points that decrease with increasing atomic number

A group of students measures the period of a pendulum while varying the pendulum length and mass. Their results are shown in the table. Which conclusion is best supported by their data? choose the two that are correct.

•  Increasing the mass of a pendulum decreases its period.
• Increasing the mass of a pendulum does not affect the period.
• Increasing the length of a pendulum Increases its period. 

• Increasing the length and the mass of a pendulum causes an increase in its period

Sun Li investigates the time for 10 grams of table salt to dissolve in 100 milliliters of water. She sets up six beakers, using the information in the table.  In which beaker would salt dissolve the slowest? Type only the number of the beaker

(a)  

A scientist studied two species of sea snail and recorded their physical characteristics in the data table. Which conclusion about the data is based on correct reasoning? Choose the best 2

• If She studies a snail and it has a brown shell then it could have a White underside OR a Red underside

• If a snail she studied had a brown shell, then it had a white underside.

• If a snail she studied was 175 millimeters long, then it had a white underside.

• If a snail she studied was 125 millimeters long, then it was red foot snail.

A scientist studying a species of flower that grows on the side of a mountain measured the height of many of the flowers at different elevations. His results are shown in the graph. Which statement best describes the pattern of growth for the flowers during this experiment?

• The flowers cannot grow below elevations of 1,500 meters.

• The flowers’ heights Decrease with elevations over 3,000

• The flowers’ heights are unaffected by elevation.

• The flowers grow taller at elevations of around 1,000 meters.
