Study Notes
Class 9 Science Chapter 1, titled "Matter in Our Surroundings" and "Matter and Its Nature" is an important chapter that teaches students about the physical properties of matter, its nature, and the various states it can exist in. The chapter is further sub-cate-
- Matter is made up of particles, and its physical nature can be classified as solid, liquid, or gas, based on interparticle forces and the arrangement of particles
- Particles of matter have spaces between them, which is one of the concepts behind the solubility of a substance in other substances
- Particles of matter are always in motion, and they possess kinetic energy, which increases with a rise in temperature, making them move more vigorously
- Particles of matter attract each other, and the strength of the force of attraction differs from one substance to another
In this chapter, students will also be taught about the states of matter, change of state of matter, evaporation, latent heat of vaporisation, and latent heat of fusion [100] [101] [102] [103] [104] [105] [106] [108] [109] [110] [111] [112] [113] [114] [115] [116] [118] [119] [120] [121] [122] [123] [124] [125] [126] [128] [129] [130] [131] [132] [133] [134] [135] [136] [138] [139] [140] [141] [142] [143] [144] [145] [146] [148] [149] [150] [151] [152] [153] [154] [155] [156] [158] [159] [160] [161] [162] [163] [164] [165] [166] [168] [169] [180] [181] [182] [183] [184] [185] [186] [188] [189] [190] [191] [192] [193] [194] [195] [196] [198] [199] [200] [201] [202] [203] [204] [205] [206] [208] [209] [210] [211] [212] [213] [214] [215] [216] [218] [219] [220] [221] [222] [223] [224] [225] [226] [228] [229] [230] [231] [232] [233] [234] [235] [236] [238] [239] [240] [241] [242] [243] [244] [245] [246] [248] [249] [250] [251] [252] [253] [254] [255] [256] [258] [259] [260] [261] [262] [263] [264] [266] [268] [269] [280] [281] [282] [283] [284] [285] [286] [288] [289] [290] [291] [292] [293] [294] [295] [296] [298] [299] [300] [301] [302] [303] [304] [305] [306] [308] [309] [310] [311] [312] [313] [314] [315] [316] [318] [319] [320] [321] [322] [323] [324] [325] [326] [328] [329] [330] [331] [332] [333] [334] [335] [336] [338] [339] [340] [341] [342] [343] [344] [345] [346] [348] [349] [350] [351] [352] [353] [354] [355] [356] [358] [359] [360] [361] [362] [363] [364] [366] [368] [369] [380] [381] [382] [383] [384] [385] [386] [388] [389] [390] [391] [392] [393] [394] [395] [396] [398] [399] [400] [401] [402] [403] [404] [405] [406] [408] [409] [410] [411] [412] [413] [414] [415] [416] [418] [419] [420] [421] [422] [423] [424] [425] [426] [428] [429] [430] [431] [432] [433] [434] [435] [436] [438] [439] [440] [441] [442] [443] [444] [445] [446] [448] [449] [450] [4
