Btw the last two you answer in your OWN words
11.) Metal is a better conductor and has a higher melting point than non-metals. Some nonmetals (such as wood and plastic), would burn/break/ben/melt under a much lower heat point than metals. It (metal) also allows food/liquid to be cooked/heated better, because it is a good conductor.
WARNING THE NEXT ANSER HAS PERSONAL INFORMATION IN IT (2nd part/paragraph), DO NOT INCULDE IT IN YOUR TEST, THIS IS JUST FOR AN EXAMPLE!!!
12.)Two components of the control system would be the steering wheel and the breaks. In the situation that the breaks subsystem would stop working, driving would be very hazardous because you could not control the car. If the steering wheel broke then the vehicle could steer into a place a car shouldn't be (example: the other lane, off the road).
When I was about 10 or so, my Dad was driving to work (I was not in the car, this is just what he told me). It was an icy day, and he was getting off of the highway on a ramp. (I forgot if his breaks were broken or they just didn't cooperate, but) My dad's breaks stopped working on the ramp when he'd tried to break, so he used another part of the car to slow himself down (the steering wheel...?......I don't remember that minor detail). No one got hurt because my Dad did not crash. (P.S. My dad is an excellent driver and even better mechanic, so he got his breaks fixed somewhere in his busy work schedule)

11. Metals are better conductors of heat and have higher melting points compared to nonmetals. This property of metals makes them useful for cooking and heating food or liquids, as they can conduct heat more efficiently and evenly.
12. The control system of a car consists of various components, including the steering wheel and brakes. If the brakes subsystem malfunctions or fails to work, it can lead to unsafe driving conditions as the driver would be unable to stop or slow down the vehicle. On the other hand, if the steering wheel breaks or becomes faulty, the car could veer off the road or into other lanes, causing a potential accident. In such cases, it is crucial to ensure that all components of the control system are functioning correctly and undergo regular maintenance to prevent such malfunctions.
