A solution in which methyl orange is red indicates the most acidic substance.

<h3>What is an Indicator?</h3>

This is defined as a substance that gives a visible sign, usually by a colour change when a chemical species is added.

On litmus paper, the redder the color is, the more acidic it is which was why methyl orange changing to darker red signifies most acidity.

2 The substance has a mass of 0.50 kg.

katen-ka-za [31]

Answer:

68000J/kg

Explanation:

Given parameters:

Mass of the substance = 0.5kg

Quantity of heat transferred to the body = 34000J

Unknown:

Specific latent heat of fusion = ?

Solution:

The specific latent heat is usually involve in phase changes;

H = mL

H is the quantity of heat supplied

m is the mass

L is the specific latent heat

Insert the parameters and solve;

34000 = 0.5 x L

L = $\frac{34000}{0.5}$ = 68000J/kg

A gas initial volume and pressure is 5m^3 and 101320 Pa and allows to expand up to 12m^3 then what is the final pressure?

Anton [14]

Answer:

New pressure = 42216.66 Pa

Explanation:

Given that,

Initial volume, V₁ = 5 m³

Final pressure, P₁ = 101320 Pa

Final volume, V₂ = 12 m³

We need to find the final pressure of the gas. We know that the relation between pressure and volume is given by :

$P\propto \dfrac{1}{V}\\\\P_1V_1=P_2V_2\\\\P_2=\dfrac{P_1V_1}{V_2}\\\\P_2=\dfrac{101320 \times 5}{12}\\\\P_2=42216.67\ Pa$

So, the new pressure is equal to 42216.66 Pa.
