The heating curve

The curve is a graphical presentation of the phase of the transition of the substance as heat is added to it. The plateau shows us the mark in the changes in the heat of the substance. The rising temperature stays constant during the phase.

Hence the answer is a horizontal line.

The heating curve is opposite to the cooling curve and it shows the temperature of the substance when the cooling takes place. The heat is refed to the thermal energy and is shown along with the graph in the form a curve.Hence the constant line with no change is a horizontally flat curve.

Thus the option C is correct.

Answer from: toxsicity

A "heating curve" is a graph that shows the temperature of the substance
against the amount of heat you put into it.

For most of the graph, as you'd expect, the temperature goes up as you
add heat, and it goes down as you take heat away. BUT ... While the
substance is changing state, its temperature doesn't change even though
you're putting heat in or taking heat out.

So that part of the graph is a horizontal line.

She sold 135 peaches, because if you multiply 2.50 eith 135, you'd get 337.5, the 0 can be added or not.

Answer from: Quest

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm. the wire diameter is d = 0.9 mm. the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2) in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
