Applications of specific heat in our daily lives

Frnd, here are some Examples of heat conduction in our daily lives-
=>A cold cast iron skillet is placed onto a stovetop. When the stove is turned on, the skillet becomes very hot due to the conduction of heat from the burner to the skillet.
=>You decide to touch the handle of the skillet after it has been on for several minutes, and now the handle is hot, too. This is because heat was conducted through the portion of the skillet in contact with the stovetop all throughout the rest of the skillet.
=>A shirt is placed on an ironing board to be ironed. Heat from the iron is conducted to the shirt, making it easy to iron out all those unsightly wrinkles and make the shirt look sharp.
=>The engine of a car is turned on, and the hood becomes warm due to the conduction of heat from the engine to the hood of the car.
=>A cube of ice is placed into the hand of a man. Over time, heat conducted from the man’s hand to the ice cube will cause the ice to melt.
=>A boy grabs a coin from his tabletop, and it feels very cold to the touch. After holding it for a few seconds, the heat from his hand is conducted to the metal coin.
=>The radiator is turned on to warm a house during a cold day, and the owner of the house puts his hat on top of it. The hat becomes warmer due to the radiator conducting heat to it.
=>A boy places a hot dog onto the end of an unraveled metal clothes hanger and begins to cook it over the fire. After a time, the hanger begins to feel hot due to the heat conducted from the hot fire all along the piece of wire

The question is related to how we make use of the physical property of specific heat of substances in our daily life to our advantage.
Specific heat or specific heat capacity s = heat capacity / mass
or, ΔQ = m s (T₂ - T₁)
Specific heat gives the amount of heat energy required for heating a substance of 1 unit mass by 1 °C. So more the specific heat, more the energy required for heating the substance.
1) Utensils used for making tea or coffee, or cooking vegetables or rice are made of materials of low specific heat. They are polished at the bottom. So they get heated quicker. For example, copper, aluminum etc.
2) Materials of high specific heat can be used as insulators. For example wood has a high specific heat. Wooden houses will keep the inside cooler during summer. Builders can choose building materials appropriately depending on the location and altitude. That allows to build warmer houses or cooler houses.
3) The handles of utensils at home are made of materials which have very high specific heat. They act as thermal insulators. The insulating capability or conductivity is also dependent on specific heat.
4) Instrument like thermometer, the body may be made of higher specific heat and the tip is made of material of low specific heat.
5) The water in swimming pool remains cool even in summer and people enjoy a lot staying inside the pool. The reason is high specific heat of water.
6) Steam has a high specific heat (more than water). Steam is used to carry a lot of heat energy at high pressures to run rail engines or rotors in AC generators.
