The document discusses density and how it relates to whether an object will sink or float in a liquid. It defines density as mass divided by volume and provides examples of calculating density using measurements of mass and volume. It explains that an object will sink if it has a higher density than the liquid, and float if it has a lower density. Examples are given of stones and glass sinking in water while ice cubes and cork float, and a table lists densities of substances to determine which would float in petrol.

This document discusses the properties of solids, liquids, and gases. Solids have a definite shape and volume, with molecules closely spaced, while liquids have no definite shape but take the shape of their container. Gases have no definite shape or volume and their particles can move freely past one another. It also discusses how increasing energy causes solids to change to liquids and liquids to change to gases. Surface tension is defined as the contractive tendency of a liquid's surface, and it influences ecosystems and allows objects to float on water.
Plastic shrinkage cracks
Plastic shrinkage cracks occur when the surface of fresh concrete dries too quickly due to rapid evaporation before the concrete has set, causing the surface to shrink more than the interior. This develops tensile stresses that can exceed the concrete's strength and cause cracking. The risk of plastic shrinkage cracking can be reduced by protecting fresh concrete from direct sun and wind, using a low-slump mix with fine sand, applying curing compounds to prevent evaporation, and timing concrete placement to avoid rapid drying conditions. Proper curing is important to ensure the surface evaporation potential is zero and prevent further cracking.
Chapter 3 (science form 1)
Matter is anything that has mass and occupies space, while non-matter does not have mass or occupy space. Matter is composed of tiny discrete particles and can exist in different states depending on the arrangement of those particles. Different types of matter, like copper sulfate crystals or air, can mix with other substances when their particles separate and diffuse between the spaces of particles in another substance.

How to measure bulk density of zircon brick
- 1. How To Measure Bulk Density Of Zircon brick? What is called bulk density? Simply put, bulk density is that the weight of zircon brick divided by the total volume of zircon brick. It is an indicator of weight for unit volume bricks. The weight can be weighed in the air directly, volume is a measure of the amount of space that an object takes up. Bulk density is a useful property of zircon brick, which can directly reflects the micro structure and influences the physical and chemical features such the resistance to slag, thermal shock resistance, cold crushing strength and corrosion resistance to glass liquid. An increase in bulk density of zircon brick will increase its volume stability, heat capacity, as well as resistance to slag penetration. How to measure bulk density of zircon brick? As to weight, it is relatively easy got as the brick can be weighed in air. However, volume is more difficult to measure as the zircon brick is quite a complicated shape and formats, it is not very evenly shaped and it has quite a rough surface. At present, a method called water displacement method which is an useful method to measure the volume of solid object. Below are the steps of water displacement method: 1. Load a certain amount of liquid into the appropriate vessel and record the volume(V1). 2. Put a zircon brick into the liquid and submerge it totally, accordingly the volume will increased, and record this volume (V2). 3. The volume of the submerged zircon brick is the same as the increased volume of liquid displaced which equals to V2 minus V1 After get the volume of zircon brick，the density can now be calculated Zhengzhou Sunrise Refractory Co., Ltd can provide zircon brick with good quality which have passed the ISO international certified. With reliable quality, competitive price and prompt delivery, Sunrise has established long-term business and cooperation relationship with many customers in different countries and regions. For any further information, Contact us, Sunrise are sincerely looking forward to establishing a long-term mutually beneficial relationship with you. Source link: http://www.zirconbrick.org/
