Question

why quilts we use in winter have a whitw colour cloth

Answer 1

We can use quilts of any colour in winter, but it should be made up of cotton . White colour usually reflects heat and light . Quilts are made with cotton because cotton contains spaces . As per as law air fills these spaces . Air being a bad conductor of heat captures the heat radiated by our body . Thus we feel warm when we wrap ourselves in it and sleep in winter . As being able to warm us it is used in quilts and we are using them in winter.
