A 25.0g tin sample was placed in boiling water at 99.5 C until it had the same temperature. Afterwards, the tin sample was place

d in room temperature water. If the tin sample lost 399.4J of heat and its final temperature was 24.5 C, what is the specific heat of tin?

Answer : The specific heat of tin is, 0.213 J/g.K

Explanation :

Formula used :

q=m\times c\times (T_{final}-T_{initial})

where,

q = amount of heat lost = -399.4 J

c = specific heat capacity of tin = ?

m = mass of tin = 25.0 g

T_{final} = final temperature = 24.5^oC=273+24.5=297.5K

T_{initial} = initial temperature = 99.5^oC=273+99.5=372.5K

Now put all the given values in the above formula, we get:

-399.4J=25.0g\times c\times (297.5-372.5)K

c=0.213J/g.K

Therefore, the specific heat of tin is, 0.213 J/g.K

What are the effects of climate change? Answer this question integrating other topics of science.
riadik2000 [5.3K]

Answer:

»Climatic change leads to malnutrition.

e.g when its cold season, osmoregulation decreases and rate of metabolism declines.

This is because the enzymes lack that optimum temperature for their catalytic activity to take place hence improper digestion.

»Leads to promotion of predation in ecosystem.

such as reptiles e.g snakes, lizards get away from shelters on cold days since they are cold blooded, hence their predators such as animals, birds increase.

Which measurement density or conductance do you believe gives a more accurate method to determine the salt concentration of a so
lakkis [162]
<span>Conductance gives a more accurate method to determine the salt concentration of a solution.Conductivity would be used with conductors such as metals that include copper and silver.Conductivity is a measure of water's capability to pass electrical flow. This ability is directly related to the concentration of ions in the water. These conductive ions come from dissolved salts and inorganic materials such as alkalis, chlorides, sulfides and carbonate compounds</span>

Answer:

C2= 0.16M

Explanation:

C1= 2M, V1= 20ml, C2= ?, V2= 250ml

Applying dilution formula

C1V1= C2V2

2×20 =C2×250

C2= 0.16M
