Question

5. How does the density changes when it is heated 4°C to 10°c?​

Answer 1

Answer:

When water is heated from 0 0C, its volume decreases because its density increases and you can see this effect upto 4 0C. Because the density of ice is maximum at 4 0C. Afterwards as the density decreases the volume increases. The main reason for this is hydrogen bond in ice gets cleaved due to the melting of ice

As the water is supplied heat energy, its molecules gain kinetic energy and start to move faster. They apply a larger force against the intermolecular forces. As they do, the liquid expands a bit that is to say its volume increases. Density is defined as:

Mass ÷ volume

So when volume increases but the mass stays same, density decreases

Answer 2

Answer:

as the water is supplied heat energy it's molecule gain kinetic energy and start to move faster they apply large force to intermolecular charge.as they liquid expand to bit that is to say it's volume increase.or density decreases.
