* Sewing machine:
A sewing machine is machine used to stitch clothes with thread.Sewing machine was invented during the first industrial revolution before than all sewing was used to be done manually consuming lots of time and efforts. Modern sewing machines are designed in such a way that the cloth glides in to it and gets stitched when it passes to the needle and glides out of it. It has great use at homes as small sewing work can be done by this machine and one can avoid going to the tailor for small tailoring works. Now a days every one has it at their home.

AC equipment normally reduces humidity of the air processed,relatively cold evaporator coil condenses water vapours from the processed air.and the water is drained out. So air conditioner creates an artificial environment for us to live in. The temperature can be manually set as per our requirements.
A microwave oven is an appliance used to heat food by using electricity. This works by using microwave radiations to heat polarized molecules in the food. This is commonly used in houses to heat food quickly and efficiently but unlike traditional ovens don't bake food.
