What evidence from the experiment shows that conduction occurred? in your answer, be sure to include the materials involved in the transfer of heat through conduction.

check explanation

Explanation:

Heat transfer is the exchange of thermal energy between physical system. Heat can be transferred through conduction, convection and radiation.

The transfer of energy in the form of heat from one atom to another is known as CONDUCTION.

The movement of molecules within fluids is known as CONVECTION.

The electromagnetic radiation produced by the motion of particles in matter is known as THERMAL RADIATION.

The EXPERIMENT INVOLVE THE MELTING OF CHOCOLATE. At a certain temperature the chocolate pieces for the experiment undergo a physical change, from a solid to a liquid. Since the pieces of Chocolate and the foil bridge are touching each other, Heat is transferred between the chocolate pieces and foil bridge.

The melting of the pieces of chocolate one by one is evidence that conduction occurred.

As heat flowed through the foil bridge, heat transferred to the pieces of chocolate, causing them to melt.

The heat transfer occurred between the foil bridge and the chocolate pieces, which were in direct contact with one another.

Explanation:

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

idk what the question is about
