What is the effect of high specific heat on temperature change?
High specific heat causes a smaller temperature change for a given amount of heat transfer.
What is the effect of high thermal conductivity on heat transfer rate?
High thermal conductivity results in a faster rate of heat transfer.
What happens when heat is added to a substance with high specific heat?
The substance's temperature increases slowly.
What happens when a material with high thermal conductivity is placed between two objects of different temperatures?
Heat is rapidly transferred from the hotter object to the colder object.
What is the effect of increasing the thickness ($L$) of a material on the rate of heat transfer?
Increasing the thickness decreases the rate of heat transfer.
What happens when a material with high specific heat is heated?
Its temperature increases slowly because it requires a large amount of energy to raise its temperature.
What happens when a material with high thermal conductivity is placed in contact with a heat source?
Heat is rapidly transferred through the material.
What is the effect of increasing the thickness ($L$) of a material on the rate of heat transfer?
Increasing the thickness decreases the rate of heat transfer.
What happens if the temperature difference ($\Delta T$) across a material increases?
The rate of heat transfer through the material increases.
What is the effect of increasing the cross-sectional area ($A$) on the rate of heat transfer?
Increasing the cross-sectional area increases the rate of heat transfer.
What is specific heat ($c$)?
The amount of energy needed to raise the temperature of 1 kg of a substance by 1°C.
What is thermal conductivity ($k$)?
A measure of how well a material conducts heat.
Define heat energy transferred ($Q$).
The amount of energy transferred due to a temperature difference (measured in Joules).
Define rate of heat transfer ($\frac{Q}{\Delta t}$).
The amount of heat energy transferred per unit of time (measured in Watts).
What is $\Delta T$ in the context of specific heat and thermal conductivity?
Change in temperature, usually measured in degrees Celsius (°C).
