“How can we use machines to heat up fluids?”
We use warm fluids in our lives every day, whether it be in the showers we take, the HVAC systems that make our homes cozy or in our electrical generators. However, how exactly can we heat up such fluids? Well, let’s use our engineering mindset to find out. We know that if left to the surroundings, the heat from a fluid will radiate out. So if we were to place this fluid into a container, then logically the heat would be trapped inside. Furthermore, let’s control the temperature of this fluid by placing the container near a combustible source as to constantly supply energy. After constructing this, we will have ourselves what engineers have termed a boiler. Such machines are vital to the operation of our infrastructure, whether it be in the engines of trains or for culinary purposes.
