1. Chemistry Warm Up List

2. Chemistry Warm Up
You place 50 g of an unknown metal with a temperature of 50 C into 200 mL of water with an initial temperature of 25 C. After the temperatures reach equilibrium, the final temperature is 33 C. Given that the specific heat capacity of water is 4.18 J/goC, calculate the specific heat capacity of the unknown metal.

3. Chemistry Warm Up
What is the difference between conduction and convection?
Can energy be transferred through gases by conduction?
What is the mass of an object with a density of 26 g/mL and a volume of 59 mL?

4. Chemistry Warm Up
You place a 20 g block of hot iron into 50 g of water. After the temperature of the block and the water reaches equilibrium, the water’s temperature increased from 25 C to 50 C.
How much heat was absorbed by the water? The specific heat capacity of water is J/(g˚C)
How much heat was lost by the iron block?

6. Where does energy in our food come from?
Photosynthesis
6 CO2 + 6 H2O + Energy  C6H12O6 + 6 O2
Cellular Respiration
C6H12O6 + 6 O2  6 CO2 + 6 H2O + Energy
