The effect of size on the effectiveness of diffusion Aim: To use agar blocks infused with 0.1 Molar sodium hydroxide (NaOH) and phenolphthalein to investigate the relationship between shape and surface area: volume ratio on the effectiveness of diffusion. Hypothesis: That for a cube of agar‚ the time taken for complete colourisation due to diffusion of HCl is directly proportional to the cubes volume. Materials: |A block of agar (10cm x 5cm x 3cm) with 0.1M NaOH and |1x 250mL

The bumpy road to low carbon development: Insights from changes in the innovation system of China’s photovoltaic industry 1 Introduction Environmental scientists‚ energy experts and relevant enterprises assure us that the technological solutions needed for low carbon development are already available. This is good news as it implies that – at least technically – it is possible to prevent global warming beyond the 2°C threshold. But what does ‗availability‘ of low carbon technologies actually

Introduction: Diffusion and osmosis are passive processes of transport. Passive transport involves no disbursement of energy by the cell. Diffusion movement is from high concentration to low concentration‚ which the driving force for this type of movement is kinetic energy particles themselves. Which crystal (Methylene blue‚ solid or Potassium Permanganate KMnO4-purple) will move further than the other due to the driving force (kinetic energy)? My prediction is that Potassium Permanganate KMnO4-

Diffusion is the molecular net movement from a higher concentration to a lower concentration. For instance‚ when a person is smoking‚ the smoke diffuses into the air. The molecules in the smoke‚ released from the cigarette‚ travel through the air. Here is how it occurs. When molecules are close enough‚ they collide with each other‚ their kinetic energy changes. Due to the direct relationship between diffusion and molecular kinetic energy‚ the molecules move away from the point of the collision as

OVERVIEW OF INNOVATION SYSTEMS Fostering Long-term Economic Growth INTRODUCTION Innovation policy studies try to understand how important innovation is in our increasingly competitive world and markets. They question government intervention to find the most effective way of helping innovation thrust forward‚ not only through private investment and subsidizing but through helping and backing up industries and firms which look as future leads for long term economic growth. When talking about

Where as the active transport requires energy from the molecule to be moved. oFacilitated diffusion can only move in one direction from high concentration to low concentration‚ which is with the gradient. Where the active transport can move from both low concentrations to high concentrations‚ therefore it can move against the gradient where as the facilitated diffusion can not. The process of active transportation is when a molecule work together with the active side of a protein

has a single theory or belief that influences the way they others. For me‚ that theory is Carl Rogers’ theory of personality‚ and this theory greatly impacts how I view others in society and in the workplace‚ in addition to my own role in society and the workplace. Carl Rogers’ theory of personality is a humanistic argument that emphasizes the basic good in all people. Boeree (2006) writes that Rogers’ theory is based on the belief that mental health is the “normal progression” of life and that
