this is because metal is no capable of having hot drinks in it
Because capsare made of metals, and when metals get hot they expand, making it bigger, and easier to unscrew
Because they won't break if you drop them. Availability of materials is another good answer.
A double-walled insulated cup made of stainless steel or ceramic will keep hot water hot the longest due to its ability to retain heat and prevent heat loss. Vacuum-sealed tumblers are also effective in maintaining the temperature of hot drinks for an extended period of time.
The spoon is likely made of a good conductor of heat, such as metal. Metals like stainless steel and copper have high thermal conductivity, allowing them to quickly absorb heat when in contact with a hot substance.
Hot working of metals is defined as a process of forming metals by deformation at temperature above the recrystallization temperature.
Hot Chisels are used for cutting metals in hot conditions. The edge of a hot chisel is 30 degree and hardening of the edge is not necessary. On the other hand cold chisels are used for cutting metals in cold conditions. The edge of a cold chisel is hardened and tempered and has an angle of about 60 degrees.
wood from the acacia and date palm trees made into charcoal. Charcoal can be made to burn hot enough to smelt metals, including iron, from their ores and to work the finished metal.
1. length of metals will be increased. 2. mercury is used in thermometer mass thermometric liquid. 3. cooking vessels are made up of metals as they are good conductors of heat. 4. copper tubing is used in automatic radiators. 5.tip of the soldering rod is made up of copper.
tongs
Hot water. Metals become more malleable at greater temperatures.
Metals get hot in car because it is a good conductor of heat. When sun rays fall on the car, car becomes hot or because of engine's heat.
Mugs made of materials such as ceramic, stainless steel, or double-walled insulated tumblers tend to keep water warmer for longer periods of time compared to mugs made of glass or thin plastic. These materials provide better insulation and help retain heat better. Double-walled insulated tumblers, in particular, are designed to keep drinks hot or cold for an extended period due to the air barrier between the walls.
