What is absolute zero? What is the temperature of absolute zero on the Kelvin and Celsius scales?
salantis [7]

Answer:

Absolute zero = 0 K or - 273°C

Explanation:

Absolute zero :

 When the entropy and enthalpy of the ideal system reach at the minimum value then the temperature at that condition is known as absolute zero condition.

Absolute temperature is the minimum temperature in the temperature scale.The value of absolute zero is 0 K.

We know that

\dfrac{C-0}{100}=\dfrac{K-273}{100}=\dfrac{F-32}{180}

F=Temperature in Fahrenheit scale

K=Temperature in Kelvin scale

C=Temperature in degree Celsius scale

When  K = 0

\dfrac{C-0}{100}=\dfrac{K-273}{100}

\dfrac{C-0}{100}=\dfrac{0-273}{100}

C= - 273°C

Absolute zero = 0 K or - 273°C

Answer:

2KOH(aq) + H2SO4(aq) ⇒ K2SO4(aq) + 2H2O(l)

Explanation:

The reaction is a neutralization reaction since an acid, aqeous H2SO4 reacts completely with an appropriate amount of alkali, aqueous KOH to produce salt, aqueous K2SO4 and liquid water, H2O only.

2KOH(aq) + H2SO4(aq) ⇒ K2SO4(aq) + 2H2O(l)

Alkali + Acid → Salt + Water.

During this reaction, 2 moles of KOH neutralize 1 mole of H2SO4 to yield 1 mole of K2SO4 and 2 moles of H2O.
