What mass of aluminum at 144 Celsius will increase the temperature of 100 g of water by from 10 C to 15 C?

Andrej [43]

Answer:

$m_{Al} = 18.019\,g$

Explanation:

There is a heating process between an aluminium piece and water, which is described by the First Law of Thermodynamics:

$Q_{Al} = - Q_{w}$

$m_{Al}\cdot c_{Al}\cdot (T_{o,Al}-T) = m_{w}\cdot c_{w}\cdot (T-T_{o,w})$

The mass of the aluminium piece is therefore cleared and known variables are substituted:

$m_{Al} = \frac{m_{w}\cdot c_{w}\cdot (T-T_{o,w})}{c_{Al}\cdot (T_{o,Al}-T)}$

$m_{Al} = \frac{(100\,g)\cdot \left(4.184\,\frac{J}{g\cdot^{\circ}C} \right)\cdot (15^{\circ}C-10^{\circ}C)}{\left(0.900\,\frac{J}{g\cdot ^{\circ}C} \right)\cdot (144^{\circ}C-15^{\circ}C)}$

$m_{Al} = 18.019\,g$

A bird flies at a speed of 15 m/s for 10 seconds, 1,200 m/min for 0.17 minute, and 2,500 cm/s for 5,000 milliseconds. What is th

DedPeter [7]

Answer:

Explanation:

average speed=distance travelled/time taken

distance=speed*time

15*10=150 m

1200 m/min=20 m/s

0.17 minute=10.2 seconds

20*10.2=204 m

2500 cm/s=25 m/s

5000 milliseconds=5 seconds

25*5=125 m

125+150+204=479 m

10.2+5+10=25.2

479/25.2=19.0

I've been stuck with this for like an hour, please help.

solniwko [45]

Explanation:

Molar mass of Hg = 200.59g/mol.

Therefore Moles = Mass / Molar mass

= 100g / (200.59g/mol) = 0.499mol.
