What does a high specific heat tell about a substance?

Answer 1
Specific heat capacity is a measure of how much heat energy a material can hold per kilogram per kelvin, its units are usually given as #"kJ kg"^-1" K"^(-1), or ("kJ")/("kg K")#.
If an object's specific heat capacity was #1"kJ kg"^-1" K"^-1#. The it will hold #1kJ# of thermal energy for every kilogram with a temperature increase of #1K#, or it will hold #1kJ# of thermal energy for every #1°K# change in temperature at a constant mass.

A high specific heat capacity means it can hold a large amount of thermal energy in for a low mass or temperature change. It is also good at keeping in thermal energy, for example:

Object: Mass = 3kg #DeltaT# = 10K S.H.C. = 3.5 #"kJ kg"^-1##"K"^-1#
Liquid: Mass = 3kg #DeltaT# = 2K S.H.C = ?
#m_oC_oDeltaT_o=m_lC_lDeltaT_l# #DeltaT_l=(m_oC_oDeltaT_o)/(m_lC_l)=(3*10*3.5)/(3*2)=17.5"kJ kg"^-1##"K"^-1#.

As you can see, because of the liquid's high S.H.C. it gained the same amount of heat energy as the object lost, with a smaller temperature change.

Answer 2

A high specific heat tells us that a substance can absorb or release a relatively large amount of heat energy without undergoing a significant change in temperature.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
