Which direction does a bimetallic strip bend when cooled?
It depends how it has been constructed
Which direction does bimetallic strip bend toward higher or lower coefficient of expansion?
Lower
What is two strips of different metals welded together causing the strip to bend when heated?
That's a "bi-metal" or "bi-metallic" strip.
Why does a bimetallic strip curve when it is heated?
A bimetallic strip consists of two metal strips fastened together. Metals are chosen that expand at different rates when the strips get hot. When one strip gets longer than the other, the combination has to bend. These strips are often used in thermostats in houses to control the house temperature. When the strip is cold, it bends one way, and as it gets hotter it bends the other way. You can build the strip into a control box so that when it is cold, it closes an electric circuit and turns on the heat. When it gets a bit warmer, it will bend away from the contact point and open the circuit, turning off the heat. It will sit there all day and night turning on the heat when it gets a little cold and turning it off again when it is warmer.
How is a bimetallic strip used in a thermostat?
A bimetallic strip is used in a thermostat, by concealing it inside. When the temperature goes up, the bimetallic strip expands, and turns on the circuit for the AC/compressor ,to make the temperature cooler inside wherever the thermostat is.Two metal strips of differing thermal expansion are bonded together. Because the expansion is different the metals expand by different amounts. When heated the strip therefore has to bend, the one with the greater expansion on the outside of the curvature. As the strip bends it can either make or break a circuit contact depending on the configuration of the circuit, switching on of off the current. The reverse is true when the strip cools again.
Does the bimetallic strip bend when heated?
yes

How could a bimetallic strip be used to help in every day life?
A bimetallic strip can be used as a thermometer or thermostat. The two metals expand at different rates which will make it bend. You can use this to find the temperature of an oven. When the temperature of the oven increases, the strip will curve and break the electrical contact which make the oven cool down. When the oven cools the bimetallic strip will become straight again and the electrical contact will be remade and the oven will begin to reheat again.
What is the principel of bimetallic strip?
A bimetallic strip is made from two combined metal strips that have different rates of expansion when heated. This causes the strip to bend and so close or open an electrical contact switch.
Which direction does bimetallic strip bend toward higher or lower coefficient of expansion?
Lower
What is a bimetic strip?
A bi-metal strip is a bimetallic strip that is used to convert temperature changes into mechanical movement. It consists of two metals that expand by different amounts when the temperature changes, so it will bend when heated.
Why is bimetallic stripes used in gadgets?
Bimetallic strips consists of two strips of fused together along their length. On one side, you'll see one metal; flip it around and you see another type. Since metals don't all expand and contract at the same rate, this bimetallic strip will be straight at only one temperature. Heat the strip up and the strip will bend because one metal will expand more than the other. This bending of the bimetallic strip is used in thermostats to regulate temperature. This strip provides a closed circuit to a heater. When it gets too hot, the strip bends and cuts off the electric current. No more heating goes on, and the strip starts to cool. When the bimetallic strip is straight again, the circuit is connected, and the heater heats up again.

What does a bimetalic strip consists of?
A bimetallic strip consists of two different metals layered together, usually steel and copper or steel and brass. These metals have different coefficients of thermal expansion, causing the strip to bend when exposed to temperature changes. This bending action is utilized in devices like thermostats to control temperature.

Why bimetallic strip bend in curve instead of showing linear expansion on heating?
If one metal expands or contracts at a different rate than the other, and they are bonded together, as they are in a bimetallic strip, a curve is inevitable - it physically has to happen, if you think about it.
