Answer:
The final temperature is 16.47°C.
Explanation:
Water
m₁= 100 g
T₁= 10 °C
Cp₁= 4.184 J/g°C
Iron
m₂= 72.4 g
T₂=100 °C
Cp₂= 0.449 J/g°C
The temperature of iron i higher than the water that is why iron will loose and water will gain the heat.
We know that
Q= m Cp ΔT
Lets take final temperature is T
m₁ Cp₁ ( T- T₁ ) = m₂ Cp₂ ( T₂ -T)
100 x 4.184 ( T- 10) = 72.4 x 0.449 ( 100 - T)
12.87 ( T- 10) = 100 - T
12.87 T - 128.7 = 100 - T
13.87 T = 128.7 + 100
T=16.47°C
The final temperature is 16.47°C.
Answer:
41 inches
Explanation:
There is 12 inches in 1 foot so times 12 and 3. Thats 36 so now do 36 + 5 that =41.
Answer:
The atomic radius <em>Decreases</em> as you move from left to right on the periodic table.
hope it helps!
I just really need points sorry for commenting
Answer: Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.
