Answer 2

1. Silver and are the best conductors of heat.

Ans. Silver is an excellent conductor of heat, while stainless steel is a poor conductor. In fact, silver is twice as good a conductor as aluminum, and nearly 10 times as good as a conductor as low-carbon steel. Copper and gold are the only metals that come close to silver in thermal conductivity.

2. Heat travels in gases by​

Ans. Thermal energy is transferred from hot places to cold places by convection. Convection occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas. ... Heat can be transmitted through empty space by thermal radiation often called infrared radiation. This is a type electromagnetic radiation .
