s) carry out following conversion C)50°c. to Kelvin (b) 293k to Celsius (C 25°C to Kelvin
6) Why more serious burns are caused by steam at 100°c
than water at same temperature ?
7) why are clothes spread out for drying ?​

Answer 1

Answer:

1) Diffusion

2)High compressibility

3) Matter is anything that has weight and takes up space. Everything you can see and touch is made up of matter. Matter exists in three main forms: solids, liquids, and gases.

4) Particulate nature of matter means that all matter is made up of tiny particles.Particles of matter are very small.

5) a)50°c= 323.15k

b) 20°c

c) 298.15k

6) Steam has more energy than boiling water at the same temperature i.e. 100 degrees celsius. So, when steam falls on the skin it condenses and produces more heat than boiling water at the same temperature.

7) When we spread the clothes, they dry faster because its surface area becomes large. Evaporation occurs faster when the surface is large.
