The ratio of the specific heat of aluminum to the specific heat of iron is 2:1. How much energy must be transferred to the alumi
erastova [34]

Given what we know about ratios, we can confirm that in comparison to the iron pan, the aluminum pan will receive twice as much heat.

<h3>Why would the aluminum pan receive double the heat?</h3>
  • This has to do with the ratio being presented.
  • A ratio of 2:1 means that for every unit of heat to the iron, the aluminum receives 2.
  • In other words, the aluminum pan receives twice as much heat when compared to the iron pan.

Therefore, we can confirm that because the ratio of heat to the aluminum in comparison to the iron pan is 2:1, this means that for every 1 unit of heat to the iron pan, the aluminum pan will receive 2. This results in double the total heat received by the aluminum pan.

The molarity (M) of an aqueous solution containing 29.8 g of sucrose, C12H22O11, in 120 mL of solution is:
Rama09 [41]

Answer:

0.726 mol·L⁻¹

Step-by-step explanation:

c = moles/litres

=====

Moles = 29.8 × 1/342.30

Moles = 0.087 06 mol

=====

Litres = 120 × 1/1000

Litres = 0.120 L

=====

c = 0.087 06/0.120

c = 0.725 mol·L⁻¹

The energy pyramid below shows a possible
ExtremeBDS [4]

Energy transfer is not an efficient process.

Explanation:

There is less amount of energy in the top of the energy pyramid than at the bottom because energy transfer is not an efficient process. During the process of energy transferring, some amount is lost and some are converted to other forms of energy.

  • The sun is the ultimate source of energy for all life in the solar system.
  • When autotrophs takes this energy, they produce food from it.
  • They use light energy from the sun to produce chemical energy in food.
  • Even this conversion process waste precious amount of energy.
  • As one goes up the pyramid, more energy is lost during the process of converting from one form to another.
