Phase Change Materials and Their Applications

What is the primary function of phase change materials in passive conductive cooling?

• To decrease the temperature of a system

• To change the color of a system

• To stabilize temperature by absorbing or releasing latent heat

• To increase the temperature of a system

Why is it important for a PCM to have a melting point above the ambient temperature?

• To ensure it remains solid at all times

• To allow it to melt quickly

• To prevent it from liquefying before the panel heats up

• To make it more reactive with metals

What is a potential drawback of using salt-based PCMs?

• They may react with metals causing corrosion

• They are too expensive

• They are not suitable for thermal storage

• They have low thermal conductivity

How do organic PCMs like paraffin compare to inorganic PCMs in terms of thermal conductivity?

• Organic PCMs have higher thermal conductivity

• Inorganic PCMs have higher thermal conductivity

• Both have the same thermal conductivity

• Organic PCMs do not conduct heat

What is a specific PCM formulation mentioned for controlling temperature in PV panels?

• Ca26 H2O Fe3 Cl26 H2O

• KCl H2O

• NaCl H2O

• MgO H2O
