What are four objects that have high specific heat capacity?
What are four objects that have low specific heat capacity?
I can only think of water and sand. Can anyone help me with the other 3 objects?
You can search for a specific heat table as easily as I can.

Certainly! Specific heat capacity is a measure of how much heat energy is required to raise the temperature of a substance. Objects with high specific heat capacity require more heat to increase their temperature, while objects with low specific heat capacity require less heat. Here are four examples of objects with high specific heat capacity:
1. Water: You already mentioned water, which is known for its high specific heat capacity. It takes a lot of energy to raise the temperature of water, making it useful for various applications, such as regulating temperature in industrial processes or maintaining stable body temperatures in organisms.
2. Ammonia: Ammonia is a gas at room temperature, but its liquid form has a relatively high specific heat capacity. This property makes it useful in refrigeration systems, as it can absorb and release heat effectively during the cooling process.
3. Mercury: Mercury is a dense liquid metal with a high specific heat capacity. It is often used in thermometers due to its ability to expand and contract with temperature changes.
4. Concrete: Concrete, commonly used in construction, also has a relatively high specific heat capacity. This property allows concrete structures to absorb and store heat during the day and release it slowly during the night, helping to regulate temperature in buildings.
Now, let's move on to objects with low specific heat capacity. Here are four examples:
1. Metals: Many metals, such as aluminum, copper, and iron, have low specific heat capacities. This property makes them excellent conductors of heat, enabling them to quickly heat up or cool down.
2. Air: Compared to solids and liquids, air has a much lower specific heat capacity. This is why air temperature tends to change more rapidly than the temperature of objects or substances.
3. Plastic: Most types of plastics, like acrylic or polypropylene, have low specific heat capacities. This characteristic allows them to heat up or cool down relatively quickly.
4. Glass: Glass is another example of a material with low specific heat capacity. It does not require much heat energy to change its temperature because it is a poor conductor of heat.
I hope these examples help you understand the concept of specific heat capacity better!
