For this question, we apply the equation:
Q = mCp ΔT
Where m is the mass of the substance, Cp is its specific heat capacity and ΔT is the temperature change.
Q = 896 x 0.45 x (5 - 94)
Q = -35884.8 Joules
So about -36 kilojoules of heat is released.

Using the documents provided, evaluate the causes of the rise of nationalism throughout the world during the period 1750-1900 CE
kirza4 [7]

Although the documents mentioned in the question are not included, we can still explain the causes of the rise of nationalism during this period using other sources.

The idea of a "nation" is a modern creation. This idea is widely different to how people thought of themselves in premodern times. Prior to the development of nationalism, people thought of themselves as subjects or followers of a leader. They also identified themselves with their family or village, rather than a large community.

Nationalism only became possible after people began feeling a connection to those who shared their own language, culture and traditions, even when they had never met them before. Two important causes of this were the ideas of liberalism and the Romantic movement.

An important catalyst for this was the rise of liberalism. Liberal ideology encouraged the idea of representation of people in government. Therefore, people began to identify themselves with the government, and to think of themselves as a common people within a political unity. The permanence of people meant that the state did not equal the ruling dynasty. Instead, the king might change, but the nation prevailed.

Nationalism was also born out of Romanticism, which encouraged a romantic view of culture, traditions and common history. It also created a romantic view of land and nationhood. Because of this, there was an attempt to redraw borders to permanently match cultural and linguistic boundaries. Moreover, nationalism encouraged the idea of self-determination.

Use the passage below to answer all parts of the question that follows.
andrezito [222]

Answer:

1. The main argument made about Indian Ocean ports is that they serve people from different parts of the world.

2. Their accommodation of different religions

3. Diffusion of religion is one similarity between the regions described in the passage and the Silk Roads.

Explanation:

From the passage, the narrator goes on to show that the Indian ports of Hormuz and Calicut served people from different Asian and Arabic countries around the globe. When he arrived at Calicut, he noted the cohabitation of Muslims and Hindus. Their tolerance of each other must have facilitated trade.

Just like the Silk Roads which served merchants from different parts of the world, thus leading to a diffusion of many aspects of culture, the Indian ports also provided the same advantage.

At 25oC three moles of a gas occupy a volume of 4.0 L at 1.9 kPa If the volume increases to 8.0 L what will the new pressure be?
ivolga24 [154]

Answer:

0.95 kPa

Explanation:

P_{1} V_{1} = P_{2}V_{2}

(4.0)(1.9) = (P_{2})(8.0)

P_{2}= 0.95 kPa

-- However, you should see that when the volume increases (doubles, in this case) you will divide the original pressure value by 2. Pressure and volume are inversely related.
