How much energy is required to raise the temperature of 3kg of iron from 20 degrees Celsius to 25 degrees Celsius

Chemistry
1 answer:
Yuri [45]3 years ago
5 0

Answer:

6750 J

Explanation:

The specific heat capacity of iron is 450 J/kg/K

Quantity of heat = mcθ; where m is the mass and c is the specific heat capacity and θ is the temperature change.

Therefore;

m = 3 kg, c = 450 J/kg/K and θ = 5°C

Quantity of heat = 3 × 450 × 5

                           <u>= 6150 Joules</u>

An important Similarly between photosynthesis and cellular respiration is that both process
adelina 88 [10]

Answer:

Similarity between photosynthesis and cellular respiration is that both process :

<u>Involve production of energy </u>

<u>Exchange of gases</u>

<u>Goes through electron chain reactions</u>

<u></u>

Explanation:

<u>Photosynthesis</u> : It is the process in which green plants containing chlorophyll prepare their food in the presence of Sunlight , water and carbon dioxide.This process occur inside chloroplast .

Here Food is prepared.Oxygen and food is produced as a result of photosynthesis .

<em><u>The electrons triggers the reaction of food formation</u></em>.

<em><u>Energy is released during photosynthesis.</u></em>

<em><u>Gaseous exchange between CO2 and O2 occur.</u></em>

<u>Respiration </u>:

It is the process in which living organism converts oxygen and food to water and carbon dioxide . Here energy is released in the form of ATP. It take place inside the mitochondria of the cell.

<u><em>Exchange of Gases occur between organism and environment.</em></u>

<em><u>Here , mitochondrial electron transport occurs to produce ATP</u></em>.

Hence , similarity between photosynthesis and cellular respiration is that both process:

<u>Involve production of energy </u>

<u>Exchange of gases(carbon dioxide and oxygen)</u>

<u>Goes through electron chain reactions</u>
