A student performs two experiences, in experience $1$ he extends his hand from the window while the car is moving. In experience $2$ he immersed his hand in a stream of water. Knowing that the heat convective coefficient of air is $100\frac{W}{m^{2.}}K$ and the heat convective coefficient of water is $1000\frac{W}{m^{2.}}K.$ The skin temperature is assumed to be $33$ C and both water and air are at $10$ C $.$ Determine in which experience he felt cooler.

a$.$ Experience $2$

b$.$ Both experiences provide the same feeling

C$.$ Experience $1$
