If the pressure of a substance is increased during a boiling process, will the temperature also increase, or will it remain cons
7nadin3 [17]

Answer:

on increasing pressure, temperature will also increase.

Explanation:

Considering the ideal gas equation as:

PV=nRT

where,  

P is the pressure

V is the volume

n is the number of moles

T is the temperature  

R is Gas constant having value = 0.0821 L.atm/K.mol

Thus, at constant volume and number of moles, Pressure of the gas is directly proportional to the temperature of  the gas.

P ∝ T

Also,  

Also, using Gay-Lussac's law,

\frac {P_1}{T_1}=\frac {P_2}{T_2}

Thus, on increasing pressure, temperature will also increase.

What role do currents play in transporting heat? How does water temperature affect land nearby?
yarga [219]

When warm currents move over cool land surface, they dissipate heat due to the temperature gradient . They hence warm up the land they blow over. If a cold current blows over warm land, the land loses heat to the current. This is how currents distribute heat across the earth.


When the current blow from water to land, the current will be warm or cold depending on the water temperatures. Therefore, they will warm up or cool the adjacent land mass.

A tight knot can be easily opened by using a long spanner. Give reason.
olga nikolaevna [1]

Answer:

Torque

Explanation:

loosening loosening a boat requires a certain amount of torque which is the product of the force acting on the wrench and the moment arm, or distance from the center of rotation at which the force is applied. the longer the handle, the last force it takes to generate the same amount of torque
