Similarities between conduction convection and radiation

1 answer:

8 0

Explanation:

While conduction is the transfer of heat energy by direct contact, convection is the movement of heat by actual motion of matter; radiation is the transfer of energy with the help of electromagnetic waves.

The matter is present around us, in three states, solid, liquid and gas. The conversion of matter from one state to another is termed as a change in state, that takes place due to the exchange of heat between the matter and its surroundings. So, heat is the transition of energy from one system to another, due to the difference in temperature, which occurs in three different ways, that are conduction, convection and radiation.

People often misconstrue, these forms of heat transfer but, they are based on diverse physical interaction to transfer energy. To study the difference between conduction, convection and radiation.

Hope this helped!

Answer:

Is an exemplar of Italian Renaissance painting.

Explanation:

the Kingdom to St. Peter is an exemplar of Italian Renaissance painting. The work was part of a large decorative program commissioned by Pope Sixtus IV in 1481 for the walls of the Sistine Chapel (the name “Sistine” being derived from Sixtus’ own name), which was then, as it is today, the pope’s private chapel in the Vatican, in Rome.

If 40.0 g of molten iron(II) oxide reacts with 10.0 g of mag-nesium, what is the mass of iron produced

vagabundo [1.1K]

Answer:

$m_{Fe}=23.0gFe$

Explanation:

Hello,

In this case, the undergoing chemical reaction is:

$FeO+Mg\rightarrow Fe+MgO$

Thus, for the given masses of reactants we should compute the limiting reactant for which we first compute the available moles of iron (II) oxide:

$n_{FeO}=40.0gFeO*\frac{1molFeO}{72gFeO} =0.556molFeO$

Next, we compute the consumed moles of iron (II) oxide by the 10.0 g of magnesium, considering their 1:1 molar ratio in the chemical reaction:

$n_{FeO}^{consumed}=10.0Mg*\frac{1molMg}{24.3gMg}*\frac{1molFeO}{1molMg}=0.412molFeO$

Therefore, we can notice there is less consumed iron (II) oxide than available for which it is in excess whereas magnesium is the limiting reactant. In such a way, the produced mass of iron turns out:

$m_{Fe}=0.412molFeO*\frac{1molFe}{1molFeO}*\frac{56gFe}{1molFe}\\ \\m_{Fe}=23.0gFe$

Regards.

What are the standard temperature and pressure conditions enthalpy is usually measured under?

oksian1 [2.3K]

The standard temperature and pressure conditions enthalpy is usually measured under are 1kPa and 273K (option A).

<h3>What is enthalpy?</h3>

Enthalpy in thermodynamics is a measure of the heat content of a chemical or physical system.

Enthalpy is the sum of the internal energy and pressure times volume It can be calculated using the following formula:

H = E + P V

Where;

H = Enthalpy

E = internal energy

P = pressure

V = volume

However, the enthalpy of a substance is usually measured under standard temperature and pressure.

The standard temperature is 273 Kelvin or K
The standard pressure is 1kPa
