What properties of matter explain why the weight of an object on the moon is different than the weight of the same object on ear

th while density remains the same
Chemistry
1 answer:
algol133 years ago
4 0

Answer:

Gravity explains this.

Explanation:

Weights and mass are different terms .

Weight is defined as the force exerting on the surface due to the mass and gravity of acceleration.

W=m*g

Here mass is related to the density of the body. So as the density would be same mass woulnt vary.

Whereas the Gravity changes due to the property of the planet.

Gravity is different for different planets and hence moon and earth have two different values.

So the mass i.e density remains same on both planets but the g value always changes hence weight is different.

Why are gases compressible
Kamila [148]

Hi my dear friend,

The atoms, ions, or molecules that make up the solid or liquid are very close together. There is no space between the individual particles, so they cannot pack together. ... Gases are compressible because most of the volume of a gas is composed of the large amounts of empty space between the gas particles.

~Thank you

Study the following reaction carefully. What classification should this reaction have? 4Al + 3O 2 2Al 2 O 3
nikitadnepr [17]

The reaction is a synthesis…

4Al + 3O_2 \longrightarrow 2Al_2O_3\\

… because <em>two substances are combining to make one other substance</em>.

4\stackrel{\hbox{0}}{\hbox{Al}} + 3\stackrel{\hbox{0}}{\hbox{O}}_2 \longrightarrow 2\stackrel{\hbox{+3}}{\hbox{Al}}_2\stackrel{\hbox{-2}}{\hbox{O}}_3\\

It is also a <em>reduction-oxidation reaction</em> because the <em>oxidation number of Al increases</em> from 0 to +3 and the <em>oxidation number of O</em> decreases from 0 to -2.

How much energy in Joules is released by burning a cheese ball that raises the temperature of
aliya0001 [1]

Answer:

1. The heat energy in Joules is 5280.22J

2. The heat energy in calories is 1261.4 calories

Explanation:

Step 1:

Data obtained from the question.

The following data were obtained from the question:

Mass of water (M) = 74.2 g

Initial temperature (T1) = 24°C

Final temperature (T2) = 41°C

Change in temperature (ΔT) = T2 - T1 = 41 - 24 = 17°C

Heat energy (Q) =?

Recall:

Specific heat capacity of water = 4.186 J/g°C

Step 2:

Determination of the energy in Joules.

This is illustrated below:

Q = MCΔT

Q = 74.2 x 4.186 x 17

Q = 5280.22J

Step 3:

Conversion of the heat energy in Joules to calories. This is illustrated below:

4.186 J = 1 calorie

Therefore, 5280.22J = 5280.22/4.186 = 1261.4 calories
