Deep mountains are forged by hard work,
When the fire started, it was idle.
Broken into pieces, not sent,
Leave innocence in the world.
Poetry of physical change: thousands of blows cut deep mountains.
Refers to digging stones from the mountain. No new substance is produced, but it is a physical change.
The poem of chemical change: If the fire burns, you should remain innocent in the world.
Refers to the white calcium oxide produced by high temperature combustion of stone.
Every night, candles will drip the wick dry (chemical and physical changes).
1, the poem of physical change
Endless forests shed leaves one after another; The endless river rolls its waves all the time.
Constant polishing turns iron bars into needles; Drip wears away the stone; constant dripping water wears through the rock—persistence leads to success
The right thing stand the test
The foot of my bed is shining so brightly. Is there frost already?
Raise my cup, I invite the bright moon, which brings me its shadow and makes us three people.
People have joys and sorrows, and the moon has ups and downs.
It's not snow in the distance, because there's a smell coming.
In August and autumn, the wind roared and rolled up my three hairs.
2. Poems of chemical change
Wildfire can't burn it out, but the spring breeze can revive it.
Back in the middle of the fire, the troops began to pursue.
Going up the mountain in bright daytime, we scan the sky for the torch of war. At yellow dusk, we drink water for our horses in the river on the border.
In addition to firecrackers, the spring breeze also brought warmth (mostly burning) to Tusu.
2. Which poems contain physical and chemical properties? "I'm not afraid of broken bones, but I want to keep my innocence in the world."
This ancient poem describes the physical and chemical properties of limestone, and the physical properties of limestone CaCO3 are hard. The word "fire" tells us that limestone is not afraid of fire, but is resistant to burning and high temperature. Naivety refers to the color in the world, so we know the physical properties of limestone: white, high hardness and high temperature resistance. Of course, we also know that limestone is generated at high temperature: CaCO3 = CaO+CO2↑ under the condition of high temperature, CaO, that is, quicklime itself is a white solid, which is resistant to fire and high temperature. When the author writes that burning bones is innocent, he should refer to quicklime. This shows that some people have been forging limestone and refining limestone in the Ming Dynasty, which shows the people of that period.
