Melting
we know that ice melts at 0 ⁰C. in the graph, at position B, the temperature is constant, which indicates that phase change is taking place there. at B , from the graph , we also notice that the temperature is constant at value 0 ⁰C. this indicates that ice at 0 ⁰C is converting to water at 0 ⁰C there at position B in the graph.
hence the correct choice is Melting.
The answer I'm going with is false
Answer: there are 6 atoms.
Explanation: 3 parts of Pb times 2 atoms per part = 6
good luck:)
Answer:
<h3>The answer is 9500 kgm/s</h3>
Explanation:
The momentum of an object can be found by using the formula
<h3>momentum = mass × velocity</h3>
From the question
mass = 950 kg
velocity = 10.0 m/s
We have
momentum = 950 × 10
We have the final answer as
<h3>9500 kgm/s</h3>
Hope this helps you
Answer:
Assuming there is no heat loss to the surrounding.
Heat lost by iron equals heat gained by water.
0.2(450)(50-x)=0.2(4200)(x-30)
x=31.94 °C
