If you have 2 of the same substance and they are at the same temperature but have a different amount, what changes?

Lina20 [59]

Answer:

The heat energy stored within them changes

Explanation:

Heat energy is a function of the mass of a body, its specific heat capacity, and its temperature.

In this case, the bodies have the same specific heat capacity since they are made from the same material and the same temperature.

To get the quantity of heat stored in a body, we need to multiply all three parameters as shown below

$Q = mC \Delta T$

An increase in mass, through an increase in the amount of substance of a material present, will cause a corresponding increase in the heat energy stored within the material

. Guillermo was finding it difficult to walk up the steps to his family’s apartment. His doctor thinks that his cells might not

morpeh [17]

Answer:

Because oxygen is the combustion fuel and glucose is the substrate needed for synthesis of energy as ATPs during cellular respiration.Therefore Guillermo lacks enough energy as ATPs in her body cells, especially skeletal muscles cells to complete the task of ascending the s steps.

For all the mitochondrial in cells(sites of energy production) to receive needed glucose,and other metabolites needed for energy synthesis; an efficient transport system is needed, so that these materials are available immediately, in required amount. This system is called circulatory system.

And for the the supply of combustion fuel (oxygen) needed for the completion of the ATP synthesis mechanisms; respiratory systems which convey oxygen from the external environments to the circulatory system through breathing mechanisms, for distribution is needed.

Thus the doctor needs to test both the circulatory and respiratory systems.

This is an incomplete question, here is a complete question.

Draw a Lewis structure for H₂O that obeys the octet rule if possible and answer the following questions based on your drawing.

For the central oxygen atom:

The number of lone pairs =

The number of single bonds =

The number of double bonds =

Answer : The Lewis structure for H₂O is shown below.

For the central oxygen atom:

The number of lone pairs = 4

The number of single bonds = 2

The number of double bonds = 0

Explanation :

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.

In the Lewis-dot structure the valance electrons are shown by 'dot'.

The representation of valence electrons of an atom by dots around the symbol of an element is said to be the Lewis-dot symbol.

In the representation of Lewis-symbol, one electron dot must put on each side of the element symbol then paired the electrons.

The given molecule is, $H_2O$

As we know that hydrogen has '1' valence electrons and oxygen has '6' valence electrons.

Therefore, the total number of valence electrons in $H_2O$ = 2(1) + 6 = 8

According to Lewis-dot structure, there are 4 number of bonding electrons and 4 number of non-bonding electrons.

For the central oxygen atom:

The number of lone pairs = 4

The number of single bonds = 2

The number of double bonds = 0
