Given :

Two chemicals Cu_2O(s) and CuO(s) .

To Find :

Are these substances same or different explain.

Solution :

It might seem that the difference is none because the atoms used in the molecules are same but in different proportion .

But , their is a lot of difference between them .

The change in configuration impacts a lot in physical as well as chemical properties .

For ex :

Cu_2O is red powder while CuO is black powder .

Cu_2O is fungicide while CuO is used in batteries .

Hence , this the required solution .

Consider the heating curve for water. A graph of the heating curve for water has time in minutes on the horizontal axis and Temp
Zolol [24]

Answer:

0°C.

Explanation:

Hello,

In this case, given the heating curve of water on the attached document, we can notice that at 0 °C the solid starts melting, which means that the melting point is reached. Melting point is known as a physical change whereby a solid changes to liquid by the addition of heat as it allows the molecules to separate to each other.

Best regards.

The absolute temperature of a gas is increased four times while maintaining a constant volume. What happens to the
weqwewe [10]

Answer:

The pressure increases by a factor of four.

Explanation:

Let's consider a gas at a given temperature and pressure (T₁, P₁). The absolute temperature of a gas is increased four times (T₂ = 4 T₁) while maintaining a constant volume. We can assess the effect on the pressure (P₂) by using Gay Lussac's law.

P₁/T₁ = P₂/T₂

P₂ = P₁ × T₂/T₁

P₂ = P₁ × 4 T₁/T₁

P₂ = 4 P₁

The pressure increases by a factor of four.
