Chemistry
1 answer:
joja [24]3 years ago
7 0
Enthalpy change = mass * specific heat capacity * temperature change

Mass is 25.0 (given)
Specific heat capacity is 2.108 (checked online)
Temperature change : none
So input these into the equation :

25.0 * 2.108 = 52.7

What are the relationships between temperature and viscosity of water?
iris [78.8K]

Explanation:

Both cohesion and molecular interchange contribute to liquid viscosity. The impact of increasing the temperature of a liquid is to reduce the cohesive forces while simultaneously increasing the rate of molecular interchange. The former effect causes a decrease in the shear stress while the latter causes it to increase.

temperature?

The viscosity of liquids decreases rapidly with an increase in temperature, and the viscosity of gases increases with an increase in temperature. Thus, upon heating, liquids flow more easily, whereas gases flow more sluggishly.
