How does the density of water changes when :(a) it is heated from 0°C to 4°C. (b) it is heated from 4°C to 10°C ? |

Answer» a). increasesb). decreasesExplanation: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 |
