Answer:
-35 degrees F
When mixed in equal parts with water (50/50), antifreeze lowers the freezing point to -35 degrees F and raises the boiling temperature to 223 degrees F. Antifreeze also includes corrosion inhibitors to protect the engine and cooling system against rust and corrosion.

Answer:
True
Explanation:
To summarise, waves carry energy. The amount of energy they carry is related to their frequency and their amplitude. The higher the frequency, the more energy, and the higher the amplitude, the more energy.
Answer:1.458 Btu
Explanation:
Given
radius of canister
Height of canister
Initial pressure
Initia ltemprature
Final pressure
as canister is rigid therefore change in volume is zero
therefore
=
=
volume of canister=
=
volume of canister=12872,038.8
now calculating mass of air
PV=mRT
substituting values
m=21.0192 gm
Therefore heat transferred =
=
=1539.052J=1.458Btu
