Final answer:
Turning on the heat with an American Standard thermostat does not automatically go to the humidity percentage; its primary function is to set and control the temperature. Additionally, the efficiency of a simple machine is always less than 100 percent due to friction that converts some input work into heat.
Step-by-step explanation:
False. When turning heat on with an American Standard thermostat, it does not automatically go to the humidity percentage. Thermostats are designed primarily to control temperature, and while some advanced models may also display or control humidity levels, the primary function when activating heating is to raise the temperature to a set level. Thermostats control the temperature in a room, not the humidity. They are designed to maintain a specific temperature by turning on or off the heating or cooling system based on the desired temperature set by the user.
The efficiency of a simple machine is always less than 100 percent because some input work is invariably converted to heat energy due to friction. This concept, relevant to physics and engineering, helps in understanding the limitations of mechanical systems and the principles of energy conservation and transformation.
