Water learned in science class that different substances release heat at different rates. He decides to test this. At home, Walt

er turns the oven to 200°F. He places three casserole dishes in it: one is made of metal, one is made of glass, and one is made of ceramic. He leaves them in the oven for an hour. He then removes them from the oven, places a single ice cube on each one, and times how long it takes the ice cube to melt. In this experiment, what is the test variable?

Answer:

The correct answer will be

Test variable or dependent variable- The time required to melt the ice cube

Explanation:

In a scientific experiment, three types of variables are kept and studied which includes: The independent variable, dependent variable and the constant variable.

Among these three, the variable to be tested is known as the dependent variable which is influenced by the independent variable which changes.

In the given question, since the experiment was performed to test the rate of the release of heat by a different substance which could be tested by measuring the rate or time required to melt the ice cube which depends on the type of casserole.

Thus, the time required to melt the ice cube is the correct answer.

Answer: The correct answer is

"The material each pan is made of"

Explanation:

In this experiment, the independent variable is the material each pan is made of. The dependent variable is how long it takes each ice cube to melt. All other variables should be kept constant, including the amount of ice put in each pan, the temperature of each pan, and the temperature of each ice cube.

<h3>Further explanation </h3>

Given

Atomic symbol

Required

Atomic composition

Solution

Atomic number = number of protons = number of electrons

Mass Number (A) is the sum of protons and neutrons

Number of protons and Number of Neutrons  in nucleus

Number of electrons in the shell

From the picture:

protons = 3

neutrons = 4

electrons = 3

atomic number = protons = electrons = 3

mass number = protons + neutrons = 3+4 = 7

H3P polar or non polar
ella [17]

Answer:

Hover for more information. Phosphine is an example of a polar molecule with non-polar bonds. ... The lone pair of electrons on phosphorus causes the molecule to be asymmetrical with respect to charge distribution and that's why the molecule is polar even though it has non-polar bonds. Its shape is trigonal pyramidal.
