Specific Heat Capacity of Water-Antifreeze Solutions
What is normal concentration? I dont know but lets take it is 50%
Specific Heat Capacity unit here is (J / g / ° C)
50% antifreeze mix at 4C: 3.33
65% antifreeze mix (dont have 70% on that table) at 4C: 3.02
So it should warm up about 10% faster |
I don't think that it would warm up 10% faster though because it won't absorb heat from the engine as quickly. Just a thought.
