Marianne designs an experiment involving electrically charged objects. She wants to know which objects will be attracted to a ne

gatively charged balloon. Identify the test variable, the outcome variable, and the control variable for this experiment.
What is the outcome variable in Marianne's experiment?

(You don't need to include the control variable or test variable, you just need to write the outcome variable in her experiment.)

Answer:

OUTCOME VARIABLE: Attraction to negatively charged balloon

Explanation:

In an experiment, two major variables must be included viz: the independent variable and the dependent variable. The independent variable also referred to as the test variable is the variable that is being changed in the experiment while the dependent or outcome variable is the variable that responds to the changes made to the independent variable. The outcome variable is the variable that is measured in an experiment.

In this experiment involving Marianne wanting to know which objects will be attracted to a negatively charged balloon. The type of objects are the independent variable while the ATTRACTION is the outcome or dependent variable as it is dependent on the type of object used.

astraxan [27]

Answer

mass of 1 mole = 18g

mass of 1 mL = 1g

the unit used is gram

Explanation:

There are two ways to find mass of water:

1st way:

If we find Mass of water for one mole of water:

For this purpose we use mole formula as below

                          no. of moles = mass in grams / molar mass

if we find mass for one mole of water:

then

no. of moles of water = 1 mol

molar mass of water = H₂O = (1x2 +1x16) = 18 g/mol

mass of water = ?

Put the value in the mole formula

          no. of moles = mass in grams / molar mass . . . . . . . . . . . . (1)

by rearranging the formula (1)

            mass in grams = no. of moles x molar mass

            mass in grams = 1 mole x 18 g/mol

            mass in grams =  18 g

So for one mole of water the mass of water is 18 g and the unit for it is gram.

2nd way:

We can find mass of water by another way too

if we find the mass 1 mL of water

then the formula will be used is

                              D = m/v

where D is density

m is the mass

and v is the volume

So

density of water for 1 mL (D) = 1 g/ml

volume of water = 1 mL

mass of water = ?

By Rearranging density formula for mass

                                m = D/v ......................... (2)

put the values in equation 2

                                m= 1gmL⁻¹ / 1 mL

                                 m= 1g

So the mass of 1mL is 1g

Which property of water makes it helpful to use in car radiators?
Zolol [24]
Water has a high specific heat. It needs to absorb 4.184 Joules of heat for one gram of water to increase its temperature by 1 degree celsius.

Water in car radiators is used as coolant because it takes longer to heat up. It needs to absorb large amount of heat energy before it changes its temperature and begins to get hot.
