When 5 grams of salt is dissolved in 95 grams of water the temperature of the solution increases 10°C how much heat is evolved the heat capacity of the solution is 1.1 cal/g°C
Total mass of solution = 5 + 95 = 100 grams
Recall that the formula for calculating the heat absorbed or released is given by
Q = mc(T2 - T1)
where
m = mass
c = specific heat capacity
(T2 - T1) = change in Temperature
Substituting,
Q = 100 * 1.1 * 10
Q = 1100 cal
Hope this helps :3
To determine the amount of heat evolved when 5 grams of salt is dissolved in 95 grams of water, we can use the formula:
Heat evolved = Mass of the solution * Specific heat capacity * Change in temperature
Given:
Mass of the solution = 5 grams of salt + 95 grams of water = 100 grams
Specific heat capacity = 1.1 cal/g°C
Change in temperature = 10°C
Substituting these values into the formula:
Heat evolved = 100 grams * 1.1 cal/g°C * 10°C
Heat evolved = 1100 cal
Therefore, the amount of heat evolved when 5 grams of salt is dissolved in 95 grams of water is 1100 calories.
To calculate the amount of heat evolved when 5 grams of salt is dissolved in 95 grams of water, we need to use the formula:
Q = m * c * ΔT
Where:
Q is the heat evolved (in calories),
m is the mass of the solution (in grams),
c is the specific heat capacity of the solution (in cal/g°C), and
ΔT is the change in temperature (in °C).
In this case, the mass of the solution is the sum of the mass of salt and the mass of water:
m = mass of salt + mass of water
= 5 g + 95 g
= 100 g
Substituting this into the formula, we have:
Q = 100 g * 1.1 cal/g°C * 10°C
= 1100 cal
Therefore, when 5 grams of salt is dissolved in 95 grams of water, the heat evolved is 1100 calories.
