A straight line on a distance va time graph represents constant speed
Answer:
ΔT = 0.78 °C
Explanation:
Given data:
Mass of Al = 9.5 g
Specific heat capacity of Al = 0.9 J/g.°C
Temperature change = ?
Heat added = 67 J
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
67 J = 9.5 g × 0.9 j/g.°C × ΔT
67 J = 85.5 j/°C × ΔT
ΔT = 67 J / 85.5 j/°C
ΔT = 0.78 °C
In the given case, the scientist should use a circle graph or pie chart.
One can dissect a circle into smaller segments, a component of the circle is known as an arc and an arc is named on the basis of its angle. A pie chart, or a circle graph, is used to visualize data and information.
A circle graph is generally used to demonstrate the outcomes of an examination in a proportional way. In a circle graph, the arcs are proportional to how many percents of the population gave a particular answer.
