Answer:
151.1J
Explanation:
Given parameters:
Mass of iron = 6.21g
Initial temperature of iron = 25°C
Final temperature of iron = 79.8°C
Unknown:
Amount of heat = ?
Solution:
The amount of heat require to cause this temperature can be determined using the expression below;
H = m c (T₂ - T₁)
H is the amount of heat
m is the mass
c is the specific heat capacity
T is the temperature
Specific heat capacity of iron 0.444J/g°C
Insert the parameters and solve;
H = 6.21 x 0.444 x (79.8 - 25)
H = 151.1J
Mass of 1 centigram is equal to 0.01 grams
So, option C is your answer!
Hope this helps!
B. by the water temperature
Explanation:
Morgan should organize her data using given water temperature.
The only variable is the time it takes to dissolve the sugar cubes at different temperatures.
- Data in an experiment should be organized using the variables in the experiment.
- The variables in the experiment are the different water temperature and the time it takes for them to dissolve.
- The size of the glass does not have any effect on the dissolution.
- The amount of sugar is the same.
- There is no amount of sugar left in the glass after the experiment
