Thermochemistry Review

If the $$\Delta H$$   is negative, what type of reaction is it?

If the system releases 150J of heat, how much heat does the surrounding absorb?

If the reaction is endothermic, how does heat flow?

Where will the heat from object A flow to FIRST? Object A has a temperature of 120 $$\degree C$$  

What does it mean if an object has a low specific heat value?

Name a substance that has a HIGH specific heat value.
