Covers the definitions of temperature and heat, including how temperature relates to average kinetic energy and how heat measures thermal energy transfer. Introduces specific heat capacity with the energy–mass–temperature relationship, then details conduction, radiation, and convection with real-world examples. Includes phase changes, emphasizing constant temperature during melting/boiling and the role of specific latent heat.","GRADE 8 - SCIENCE\nJANUARY 30, 2030\nMR. CAIUS SANCHEZ\nHEAT AND TEMPERATURE\nUnderstanding how heat flows and temperature changes\nWHAT YOU’LL LEARN TODAY\nHeat and Temperature\nSpecific Heat Capacity\nMethods of Heat Transfer\nPhase Change\nSpecific Latent Heat\nTWO TRUTHS AND A LIE\nRead each statement carefully and guess which one is a lie\nHEAT ALWAYS MOVES FROM COLD TO HOT.\nBOILING WATER HAS A HIGHER TEMPERATURE THAN WARM BATHWATER.\nMETAL CONDUCTS HEAT FASTER THAN WOOD.\nWHAT IS TEMPERATURE?\nTells how hot or cold something is\nRefers to the average kinetic energy of moving particles in a substance\nMeasured in Celsius (°C), Fahrenheit (°F), or Kelvin (K)\nWHAT IS HEAT?\nMeasures the thermal energy contained in an object\nMoves from a hotter object to\na colder one\nUses the unit joules (J)\nIt is the energy required to raise one kilogram of a material by one degree Celsius (°C).\nSPECIFIC HEAT CAPACITY\nHeat (J)\nmass (kg)\nspecific heat (J/kg°C)\nchange in temperature (°C)\nWAYS OF HEAT TRANSFER\nCONDUCTION\nRADIATION\nCONVECTION\nHappens through direct contact\nOccurs mostly in solids\nTransfers heat through electromagnetic waves\nExample: how the Sun warms Earth\nInvolves the movement of liquids and gases\nTransfers heat through currents\nTHINK ABOUT IT:\nTHE VACUUM FLASK\nA vacuum flask keeps hot drinks hot and cold drinks cold. It usually has:\nA vacuum between two glass walls\nA silvered surface\nA tight cap\nHow do these features stop heat from escaping through conduction, convection, and radiation?\nWHAT HAPPENS DURING A PHASE CHANGE?\nCHANGE OF PHASE\nWhen substances are heated or cooled, they can change from one state to another. During a phase change, temperature stays the same.\nEXAMPLES OF PHASE CHANGE\nMELTING\nBOILING\nSolid turns into liquid\nLiquid turns into gas\nIt is the energy needed to change the phase of 1 kg of a substance without changing its temperature.\nSPECIFIC LATENT HEAT\nHeat (J)\nmass (kg)\nlatent heat of vaporization or fusion (J/kg)\nLET’S RECAP\nTemperature shows how hot or cold something is.\nSpecific heat capacity is the energy needed to raise the temperature of 1 kg of a material by 1°C.\nHeat flows from a hotter object to a colder one.\nHeat flows from a hotter object to a colder one.\nPhase changes happen without a change in temperature.\nSpecific latent heat is the energy needed to change the phase of 1 kg of a substance, without changing its temperature.\nUse these in your presentation.
