Why would a large iceberg have more thermal energy than a cup of boiling water?

Answers

Answer 1
Answer:

Answer:

Answer: Boiling water has a lot more heat than the oven's air (even though the air has a higher temperature). ... The iceberg has more heat than the match because it is SO MUCH LARGER, so all of its slow moving molecules have more total kinetic energy than the match's molecules.

What does percent composition tell you about a substance

Answers

Explanation:

Percentage composition tells you the percentage of each element present in a compound or molecule. This allows you to work out the number of atoms of each element present in the molecule.  Percent composition is important because it allows us to determine the percentage of each element that makes up a specific compound. Percent composition is important because it allows us to determine the percentage of each element that makes up a specific compound.

It tells you what the substance is made of.

Explanation:

Gasoline is a mixture of compounds. A gasoline sample was found to be 2.851% (by mass) octane (C₈H₁₈). 482.6 g of gasoline is combusted to produce gaseous carbon dioxide and gaseous water.Write out the balanced combustion reaction of octane with oxygen gas to form carbon dioxide and water. Submit an image of the balanced reaction.
Show all work.

Answers

Answer:

See below.

Explanation:

The mass of octane in the sample of gasoline is 0.02851 * 482.6 =  13.759 g of octane.

The balanced equation is:

2C8H18(l)  +  25O2(g) ---->  16CO2(g)  +   18H2O(g)

From the equation, using  atomic masses:

228.29 g of  octane forms 704 g of CO2 and 324.3 g of H2O

So the mass of CO2 formed from the combustion of 13.759 g of octane = (704 * 13.759) / 228.29

= 42.43 g of CO2.

Amount of water = 324.3 * 13.759) / 228.29

= 19.55 g of H2O.

2.
The initial ___________ energy is equal to zero because the starting point is set at zero height to make things easier.


kinetic
potential
3.
In the example, the final kinetic energy is determined to be ___________ because at the peak height, the ball instantaneously stops.


positive
zero
negative
4.
In this system, potential and kinetic energy are ________________ proportional.


inversely
directly

Answers

The system has an energy that can be conserved in the system, and when work is performed, the energy has been converted to working energy.

The following sentences can be completed as:

  • The total energy in a mechanical system is determined by adding the potential and kinetic energy together.

Total energy = Potential energy + Kinetic energy

  • The initial Kinetic energy is equal to zero because the starting point is set at zero height to make things easier.

  • In the example, the final kinetic energy is determined to be zero because, at the peak height, the ball instantaneously stops.

  • In this system, potential and kinetic energy are inversely proportional.

Answer:

1)total, 2)potential, 3)zero, 4)inversely.

Explanation:

1) The total energy in a mechanical system is determined by adding the potential and kinetic energy together.

2) The initial potential energy is equal to zero because the starting point is set at zero height to make things easier.

3) In the example, the final kinetic energy is determined to be zero because at the peak height, the ball instantaneously stops.

4) In this system, potential and kinetic energy are inversely proportional.

explain what force caused the movement of the continets from one supercontinet to their present positions

Answers

convection currents in the mantle. heat rises, cool drops.
This was caused by plate tectonics. Convection currents caused by the magma flowing in the mantle, slowly spread the continents apart. FACT: The continents are still moving due to the convection currents in the mantle! Millions of years from now, there may be another super continent! And it will be a cycle!

If you have a density of 3g/ml and volume of 10mL.what is the mass?

Answers

Answer:

Mass, m = 30 grams

Explanation:

It is given that,

Density of an object, d=3\ g/ml

Volume occupies by the silver, V=10\ ml

We need to find the mass of a piece of silver. The mathematical formula for the density is given by :

d=(m)/(V)

m=d* V

m=3\ g/ml* 10\ ml

m = 30 grams

So, the mass of the piece of the silver is 30 grams. Hence, this is the required solution.

The density of a Material

The density of a material is defined as the mass per unit volume

it formula is given as

Density = Mass/Volume

and the unit is g/cm^3

Explanation:

Given data

Mass = ???

Volume = 10mL

Density =  3g/ml

Hence the mass is expressed as

Mass=  density /Volume

Mass= 3/10

Mass= 0.3g

Therefore the Mass is 0.3g
