Answer: 5040 joules

Explanation:

How much energy is released when 150g of silver cools from 220°C to 80°C?

Given the following :

Mass (m) of silver = 150g

Change in temperature (ΔT) = (220 - 80)°C = 140°C

Q=mcΔT

Where Q = quantity of heat

m = mass of silver ; c = specific heat capacity

Specific heat capacity of silver = 0.240 j/g°C

Q = (150 * 0.240 * 140)

Q = 5040J

How did glaciers change the land of the Northeast region
Alekssandra [29.7K]

“Glaciers not only transport material as they move, but they also sculpt and carve away the land beneath them. A glacier's weight, combined with its gradual movement, can drastically reshape the landscape over hundreds or even thousands of years. The ice erodes the land surface and carries the broken rocks and soil debris far from their original places, resulting in some interesting glacial landforms.” nsidc.org

If a 30 °C air parcel rises from sea level to 3000 meters altitude and cools at the dry adiabatic rate, what will be its tempera
Dmitry [639]

Answer:

0^\circ C

Explanation:

Dry adiabatic lapse rate is defined as:

\Gamma = 9.8 ^\circ C/km

The air rises 3000 m, that is 3 km.

If it cools 9.8 ^\circ C each km its temperature drops approximately 30 ^\circ C. From 30 to 0.

6. Why does the north-east coast of Canada remain icebound during the winter
kow [346]

The North East coast of Canada remains icebound during winter

because of forcing of the air. As the North East coast of Canada is

located near to Northern poles and is nearer to sea hence the ports of

eastern coast of Canada freezes and the temperature in that area

becomes less than zero degree during the winter time.

Ocean currents are horizontal continuous flow of water from one place

to other . There are two types of ocean currents warm and cold flowing

along the coastline which will have an impact on climate. Thus these

waters are cold and tend to freeze up the ports early in winters.
