Because it helps the filament from decaying
Answer:
The specific heat of gold is 0.129 J/g°C
Explanation:
Step 1: Data given
Mass of gold = 15.3 grams
Heat absorbed = 87.2 J
Initial temperature = 35.0 °C
Final temperature = 79.2 °C
Step 2:
Q = m*c*ΔT
⇒ Q =the heat absorbed = 87.2 J
⇒ m = the mass of gold = 15.3 grams
⇒ c = the specific heat of gold = TO BE DETERMINED
⇒ ΔT = The change in temperature = T2 - T1 = 79.2 - 35.0 = 44.2 °C
87.2 J = 15.3g * c * 44.2°C
c = 87.2 / (15.3 * 44.2)
c = 0.129 J/g°C
The specific heat of gold is 0.129 J/g°C
Answer:
1.Magnetosphere
2.Liquid Outer core
3.Atmosphere
4.Lightening
5.Biosphere
6.Blue
7.Dolphins
8.Hydrosphere
9.Ice Caps
10.Lithosphere
11.Latitude
12.Longitude
Explanation:
The invisible field that protect us from solar radiation is called Magnetosphere.
This protective field is created by movement between solid inner core and earth's Liquid outer core.
The layer of gases is called atmosphere.
In addition to wind , rain , lightening is observed on stormy night.
Because of water earth looks Blue.
Dolphins are just one of the animals that calls the hydrosphere, its home.
Ice caps in the north and south poles.
Rocky layer of solid earth is part of Lithosphere.
Look for the latitude first ,horizontal line ...
Heat is needed to change solid to liquid even to gas!
