Disadvantages and advantages of ferrous metals?
Advantages of ferrous metals include their high strength, durability, and magnetic properties. However, disadvantages may include susceptibility to corrosion, heavier weight compared to non-ferrous metals, and limited formability.
Paint advantages and disadvantages?
It covers and protects woods and metals from the elements. It also adds colour.
What is temperature measured to?
Temperature is usually measured via expansion/contraction of a liquid (liquid thermometer), differences in expansion/contraction of two metals (bi-metallic strip thermometer), changes in electrical resistance (thermistor or thermocouple) or radiant energy (for example: a pyrometer)
What are the advantages and disadvantages of a bimetallic strip thermometer?
Advantages: Bimetallic strip thermometers are durable, have a wide temperature range, and provide accurate temperature readings due to the thermal expansion of the metals. Disadvantages: They can be slow to respond to temperature changes, may require recalibration over time, and are limited in their application to specific temperature ranges.
What is measured using temperature?
Temperature is usually measured via expansion/contraction of a liquid (liquid thermometer), differences in expansion/contraction of two metals (bi-metallic strip thermometer), changes in electrical resistance (thermistor or thermocouple) or radiant energy (for example: a pyrometer)

What are advantages and disadvantages of ferrous metals?
Advantages of ferrous metals High strength to weight ratio compared to Non-metals Heavier than Aluminum and Titanium Alloys High quality and durable material Prone to corrosion by rusting (except stainless steel) Machine-ability Affected by magnetic field Recyclable and environmentally friendly Disadvantages of ferrous metals Requires more energy to form into shapes or re-work compared to Aluminum Alloys
Which two metals are used in a bimetallic strip?
The two metals commonly used in a bimetallic strip are steel and copper. These metals have different coefficients of thermal expansion, causing the strip to bend when heated or cooled due to the uneven expansion and contraction of the metals.
What are advantages and disadvantages of nonferrous metals?
Disadvantages- may be more expensive and not as strong as ferrous metals.Advantages- may be a better electrical conductor, not affected by magnetism, may be corrosion resistant.
What are the advantages and disadvantages of tig welding?
Advantages Can be used to weld almost any metal as well as dissimilar metals. Gives very good quality welds (structurally and appearance) No slag involved Disadvantages Slow requires high skill to master
What are the advantages and disadvantages of using metal in bicycles?
It's strong enough, light enough and cheap enough. Iron-based metals might rust, and it costs a fair bit in energy and pollution to produce metals.
Why do metals expand when hot and contract when cooled?
When metals are heated, the atoms within the metal vibrate more rapidly, causing them to take up more space and the metal to expand. When the metal is cooled, the atoms vibrate less, allowing them to move closer together, resulting in contraction. This expansion and contraction is due to the changes in the spacing and movement of the atoms within the metal structure.
