Vacuum gap between glass walls e Parafuso de Arquimedes: o que têm em comum

1. Passo 1. Vacuum gap between glass walls — faz parte de — Vaso de Dewar. It does not conduct heat.
2. Passo 2. Vaso de Dewar — utiliza — Vacuum. A vacuum.
3. Passo 3. Vacuum — é utilizado em — Newcomen engine. Condensing the steam creates a vacuum under the piston.
4. Passo 4. Newcomen engine — evoluiu para — Watt steam engine. Watt improved Newcomen’s engine.
5. Passo 5. Watt steam engine — tem como parte — Manivela. The stroke of the piston becomes rotation of a shaft (Watt first used a planetary gear).
6. Passo 6. Manivela — faz parte de — Parafuso de Arquimedes. A handle or rotary drive.
