A copper of calorimeter weighs 100g when empty and 200g when half filled with water at 20 degree celcious 5g of steam is pass into the calorimeter untill the final steady of temperatur 54 degree celcious is reach neglecting heat lost to the surrounding calculate the sp.l.h of the steam take sp.c.h of water 4200j/kg/k and sp.h.c of calorimeter 400j/kg/j
Well, well, well! It seems like we have a calorimetry problem on our hands. Let's see if we can clown around with the numbers and find a solution!
First, let's start by calculating the heat absorbed by the water, since it undergoes a temperature change from 20°C to 54°C.
The heat absorbed by water can be calculated using the formula:
Q = m * c * ΔT
Where:
Q is the heat absorbed (in joules),
m is the mass of the water (in kilograms),
c is the specific heat capacity of water (4200 J/kg/°C), and
ΔT is the change in temperature (54°C - 20°C).
Since the calorimeter is already half filled with water, we need to determine the mass of the water in the calorimeter. The increase in weight of the calorimeter is 200g - 100g = 100g, which is equivalent to 0.1kg.
The mass of the water is then 0.1kg * 2 (since the calorimeter is half-filled) = 0.2kg.
Now let's calculate the heat absorbed by the water:
Q = 0.2kg * 4200 J/kg/°C * (54°C - 20°C)
Q = 0.2kg * 4200 J/kg/°C * 34°C
Q = 28560 J
Now that we have the total heat absorbed by the water, let's figure out the heat required to convert the steam into water at 100°C (which is the standard boiling point).
The heat required to convert steam into water is given by the formula:
Q = m * L
Where:
Q is the heat required (in joules),
m is the mass of the steam (in kilograms), and
L is the specific latent heat of steam.
The mass of the steam is given as 5g, which is equivalent to 0.005kg.
We need to determine the specific latent heat of steam, so let's subtract the specific heat capacity of the calorimeter from the total heat absorbed by the water:
Q = 28560 J - 0.2kg * 400 J/kg/°C * (54°C - 20°C)
Q = 28560 J - 0.2kg * 400 J/kg/°C * 34°C
Q = 28560 J - 21760 J
Q = 6800 J
Finally, let's calculate the specific latent heat of steam:
Q = 0.005kg * L
L = Q / 0.005kg
L = 6800 J / 0.005kg
L = 1,360,000 J/kg
So, the specific latent heat of steam is approximately 1,360,000 J/kg. Keep it cool and remember, when in doubt, just ask a (clown) bot!
To calculate the specific latent heat (sp.l.h) of steam, we need to use the formula:
Q = (m_water * c_water * ΔT_water) + (m_calorimeter * c_calorimeter * ΔT_calorimeter) + (m_steam * sp.l.h)
where:
Q = total heat gained by the system
m_water = mass of water
c_water = specific heat capacity of water
ΔT_water = change in temperature of water
m_calorimeter = mass of calorimeter
c_calorimeter = specific heat capacity of calorimeter
ΔT_calorimeter = change in temperature of calorimeter
m_steam = mass of steam
sp.l.h = specific latent heat of steam
Given:
m_water = 100g (when empty)
m_calorimeter = 200g (when half-filled with water)
ΔT_water = 54°C - 20°C = 34°C
ΔT_calorimeter = 54°C - 20°C = 34°C
c_water = 4200 J/kg/°C
c_calorimeter = 400 J/kg/°C
First, let's calculate the mass of water:
m_water = m_calorimeter - m_empty = 200g - 100g = 100g
Now, we can substitute the values into the formula and solve for the specific latent heat (sp.l.h):
Q = (100g * 4200 J/kg/°C * 34°C) + (200g * 400 J/kg/°C * 34°C) + (5g * sp.l.h)
Since the calorimeter is insulated, we can assume that no heat is lost to the surroundings. Therefore, the total heat gained by the system (Q) is equal to the heat gained by the water and the calorimeter, which is equal to the heat lost by the steam.
Q = 100g * 4200 J/kg/°C * 34°C + 200g * 400 J/kg/°C * 34°C
We also know that 5g of steam is passed into the calorimeter, so:
Q = 5g * sp.l.h
Now we can equate the two equations:
100g * 4200 J/kg/°C * 34°C + 200g * 400 J/kg/°C * 34°C = 5g * sp.l.h
Simplifying further:
100 * 4200 * 34 + 200 * 400 * 34 = 5 * sp.l.h
Solving for sp.l.h:
sp.l.h = (100 * 4200 * 34 + 200 * 400 * 34) / 5
Therefore, the specific latent heat of steam can be calculated using the given values and the formula.
To calculate the specific latent heat of steam, we need to determine the amount of heat absorbed by the water and the calorimeter.
First, let's find the mass of water in the calorimeter when it's half-filled:
Mass of water = (weight of calorimeter when half-filled - weight of empty calorimeter) = (200g - 100g) = 100g
Next, let's calculate the heat absorbed by the water:
Q1 = mass of water * specific heat capacity of water * change in temperature
Q1 = 100g * 4200 J/kg/K * (54°C - 20°C)
Now, let's calculate the heat absorbed by the calorimeter:
Q2 = mass of calorimeter * specific heat capacity of calorimeter * change in temperature
Q2 = 100g * 400 J/kg/K * (54°C - 20°C)
Since no heat is lost to the surrounding, the heat absorbed by the water and the calorimeter is equal to the heat released by the steam:
Q1 + Q2 = mass of steam * specific latent heat of steam
Now let's rearrange the equation to find the specific latent heat of steam:
specific latent heat of steam = (Q1 + Q2) / mass of steam
Note: We need the mass of steam to proceed with the calculation. It is not given in the information provided.
