Dry ice is solid carbon dioxide that sublimates directly from a solid to a gas at -109.3°F without passing through a liquid state. It produces a "smoke" as it sublimates due to the extreme cold temperatures. At the triple point, dry ice can simultaneously exist in equilibrium as a solid, liquid, or gas when under a specific temperature and pressure.

POPULATION DYNAMICS FOR IGCSE CAMBRIDGEYonas Gemeda
this presentation will try to discuss population change through natural and manmade features and its cause and effects on the environment and its inhabitant
We are the students of Ahsanullah University of Science And Technology from civil Engineering department .We have prepared a presentation for our Environmental Engineering lll course to explain global warming and climate change.Global Warming and Climate Change is hot topic nowadays .So this presentation was made to discover main causes behind this situation . Is Anthropogenic or natural?? In this presentation we have tried to explain this .
Photosynthesis is the process of preparing organic food (carbohydrate) by combining carbon dioxide and water, using solar energy by chlorophyll pigments.
The sugar produced in photosynthesis is stored in the form of starch in plants and it is the source of reserved internal energy.
Requirements for photosynthesis
(1) Sunlight (2) Photosynthetic pigment (3) Carbon dioxide
(4) Water
Stomata
These are tiny pores or microscopic aperture guarded by two kidney shaped r or bean shaped
guard cells,
Functions of stomata
(i) Massive amount of gaseous exchange takes place in the leaves through stomata. Exchange of gases also occurs across the surface of stem, root and leaves.
(ii) Transpiration takes place through the stomata. Large amount of water is lost in the form of water vapour through stomata is known as transpiration.
Guard cells
These are kidney shaped cells which cover single stoma. They contain chloroplast also.
Function of guard cells
They regulate the opening and closing of the stoma and also perform photosynthesis.
Opening and closing of stomata
When the guard cells swell (turgid) due to the entry of water, the stomata open. But when the
guard cells shrink (flaccid) due to the loss of water, the stomata gets closed.
Mechanism of photosynthesis
During photosynthesis following events occur
(i) Absorption of light energy by chlorophylls.
(ii) Conversion of light energy into chemical energy and splitting of water molecule into hydrogen and O2.
(iii) Hydrogen reduces CO2 and synthesizes glucose (reduction of CO2 in to carbohydrates).
All these events can be categorised into two main phases, light phase and dark phase.

Winter ecology notes frost, snow, and icemikelink45
The basic aspects of winter revolve around water and how it freezes and how our bodies try to prevent its freezing. In the exterior world ice, frost, snow are expressions of the winter season.
Matter- Matter is anything which occupies space and has mass is called matter. Air and water, sugar and sand, hydrogen and oxygen etc. Matter is made up of very small tiny particles. Particles of matter have space between them they attract each other.

As a business owner, I understand the importance of having a strong online presence and leveraging various digital platforms to reach and engage with your target audience. One often overlooked yet highly valuable asset in this regard is the humble Yahoo account. While many may perceive Yahoo as a relic of the past, the truth is that these accounts still hold immense potential for businesses of all sizes.
Implicitly or explicitly all competing businesses employ a strategy to select a mix
of marketing resources. Formulating such competitive strategies fundamentally
involves recognizing relationships between elements of the marketing mix (e.g.,
price and product quality), as well as assessing competitive and market conditions
(i.e., industry structure in the language of economics).
