Answer:GLACIERS ARE MADE UP OF FALLEN SNOW OVER MILLION YEARS, IN MOST OF POLAR REGIONS IT TURNS TO ICE AND WILL FLOW DOWNWARDS AND OUTWARDS UNDER ITS OWN PRESSURE
AND THE LARGEST GLACIER IN THE WORLD IS 60 MILES WIDE AND AROUND 270 MILES LONG.
IT COVERS 10% OF EARTH'S TOTAL LAND
Explanation:
By law of conservation of energy, the amount of heat lost
by the metal should be equal to the amount of heat gained by water. That is,
the change in energy (expressed in enthalpies) should be equal:
- (ΔH)metal = (ΔH)water
Take note of the negative sign in front of (ΔH)metal, this
means that heat is lost by this metal.
Where ΔH or change in enthalpy is:
ΔH = m Cp (T2 – T1)
So,
- 15 g (Cp) (23 °C – 99 °C) = 75 g (4.18 J/g * °C) (26 °C –
23 °C)
1,140 Cp = 940.5
