Answer: 1,013.32 cal × 4.18 J/cal = 4,235.68 J
Explanation:
1) Data:
Water ⇒ C = 1 cal/g°C
m = 65.8 g
Ti = 31.5°C
Tf = 36.9°C
Heat, Q = ?
2) Formula:
Q = mCΔT
3) Calculations:
Q = 65.8g × 1 cal/g°C × (46.9°C - 31.5°C) = 1,013.2 cal
4) You can convert from calories to Joules using the conversion factor:
1 cal = 4.18 J
⇒ 1,013.32 cal × 4.18 J/cal = 4,235.68 J
Answer:
1 Atm
Explanation:
Dalton's law
The total pressure is 3 Atm so all you have to do is subtract the other partial pressures from 3
Answer: A index fossil is any animal or plant preserved in the rock record of the earth that is characteristic of a particular span of geologic time or environment. A useful index fossil must be distinctive or easily recognizable, abundant, and have a wide geographic distribution and a short range through time.
Explanation:
Inequalities are mathematical expressions that include more than one mathematical value for which they are true. In this case, all temperatures greater than the boiling point of water are satisfactory for the expression. The boiling point of water is 100 °C, so the inequality becomes:
t > 100 °C
Answer:
(B) Movement depends on the balance between accumulation and wastage.
Explanation:
A Glacier is accumulation of snow over a particular region over many years. It is balanced by zone of accumulation and zone of wastage. The zone of accumulation is the top of the glacier where the snow or ice accumulates whereas the zone of wastage is the bottom region of the glacier which melts slowly over time. A glacier sustains if the zone of accumulation is greater than the zone of wastage.
